Abstract:

Abstract This research aims to investigate the characterization of pyrolysis oil products derived from plastic waste using FTIR (Fourier Transform Infrared) and GC-MS (Gas Chromatography-Mass Spectrometry) techniques. Plastic waste samples were subjected to pyrolysis, and the resulting pyrolysis oils were analyzed using FTIR to identify the functional groups present in the oil product. Additionally, GC-MS analysis was performed to obtain detailed information about the composition of the pyrolysis oils. The FTIR spectra revealed the presence of various functional groups, indicating the complexity of the pyrolysis oil composition. The functional groups identified in the pyrolysis oil included methyl C-H stretch and C-C stretch. The GC-MS analysis provided insights into the specific compounds present in the pyrolysis oils. The results demonstrate the potential of pyrolysis as a method for converting plastic waste into valuable oil products. The characterization of these products using FTIR and GC-MS techniques provides valuable information for further optimization and utilization of pyrolysis oil derived from plastic waste.

Abstract:

Molecular spectroscopic detection techniques, such as Fourier transform infrared spectroscopy (FTIR), provides additional specificity for isomers where often mass spectrometry (MS) fails, due to similar fragmentation patterns. A hyphenated system of gas chromatography (GC) with FTIR via a light-pipe interface is reported in this study to explore a number of GC–FTIR analytical capabilities. Various compound classes were analyzed—aromatics, essential oils and oximes. Variation in chromatographic peak parameters due to the light-pipe was observed via sequentially-located flame ionization detection data. Unique FTIR spectra were observed for separated mixtures of essential oil isomers having similar mass spectra. Presentation of GC×FTIR allows a ‘comprehensive’-style experiment to be developed. This was used to obtain spectroscopic/separation profiles for interconverting oxime species with their individual spectra in the overlap region being displayed on a color contour plot. Partial least square regression provides multivariate quantitative analysis of co-eluting cresol isomers derived from GC–FTIR data. The model resulted in an R2 of 0.99. Prediction was obtained with R2 prediction value of 0.88 and RMSEP of 0.57, confirming the method’s suitability. This study explores the potential of GC–FTIR hyphenation and re-iterates its value to derive unambiguous and detailed molecular information which is complementary to MS.

Abstract:

This study aims to investigate the chemical stability of some modern paint samples exposed to a new Light Emitting Diode (LED)-lighting system and a halogen lamp by using micro-attenuated total reflectance of Fourier transform infrared spectroscopy (µ-ATR-FTIR), µ-Raman, pyrolysis—gas chromatography/mass spectrometry (Py-GC/MS), and thermally assisted hydrolysis and methylation of GC/MS (THM-GC/MS). Those investigations were performed before and after the exposure of the samples to lightings for 1250, 2400, 3300, and 5000 h. The results obtained with µ-Raman spectroscopy show the high stability of the selected inorganic pigments after the exposure to the lighting systems; while similar to the UV/Vis/NIR results reported in a previous study, µ-ATR-FTIR and THM-GC/MS results evidence greater chemical changes occurring principally on the linseed oil binder-based mock-ups among the acrylic and alkyd-based samples. Moreover, principal component analyses (PCA) and hierarchical cluster analyses (HCA) of THM-GC/MS results highlight that those changes were mostly dependent on the exposure time and on the type of pigment, while being independent of the lighting system used. Finally, semi-quantitative µ-ATR-FTIR results show slight pigment enrichment at the paint surface due to the auto and photo-oxidative degradation of the linseed oil binder.

Abstract:

To prevent deleterious effects on consumers and potential health damage caused by counterfeit perfumes, this study aims to distinguish the original perfume from its suspected counterfeit products. Fingerprint and volatilomics profiling was performed using attenuated total reflection-Fourier infrared spectroscopy (ATR-FTIR) and gas chromatography hyphenated to mass spectrometry (GC-MS). Headspace (HS)-GC-MS was optimized to analyze perfume samples containing water. In the presence of water, our optimized HS-GC-MS method shows linalool's consistent signal intensity, providing an alternative analytical method for water-based perfume formulation. The GC-MS chemical characterization revealed 45 compounds detected in the original sample but only four compounds were detected in the counterfeit products: linalool, citronellol, methyl jasmonate, acetic acid, and propanol. This suggests a clear difference in the formulation of counterfeit products. Counterfeit products also cheat by using a lower amount of ingredients. Relative quantification shows that linalool in counterfeit products was as low as only 5.1% of the amount in the original product. In addition, cheaper and hazardous materials like methanol and 6,7-dihydrogeraniol were detected in counterfeit products. The combination of ATR-FTIR, GC-MS, and HS-GC-MS demonstrated fast authentication of counterfeit perfumes for routine quality control purposes and the possibility of water-based perfume analysis.

Abstract:

Characterization of nonpolar organic compounds of macroalga Padina minor from Singkawang waters and activity against Staphylococcus aureus and Escherichia coli bacteria has been carried out. The stages of this research consisted of maceration, fractionation, phytochemical tests, characterization using FTIR and GC-MS, as well as testing the antibacterial activity with the well-diffusion method. The fractionation process produces n-hexane, dichloromethane, and methanol fractions. The n-hexane fraction was selected for packaging using gradient n-hexane: dichloromethane eluent and yielded 11 combined fractions (F1RW1-F1RW11). The combined fraction F1RW2 was separated again using n-hexane: dichloromethane eluent in a gradient manner and 18 combined fractions (F2RW1-F2RW18) were obtained. Then the F2RW4 isolate was characterized for GC-MS characterization and the F2RW3 isolate was characterized using FTIR. The FTIR interpretation results show the absorption of hydroxyl groups O-H (345.65 cm-1), C=O (1743.65 cm-1), C=C bonds (1633.71 cm-1), C-H (2926.01; 2854.01, 1438.9 and 723.31 cm-1), and C-O-C bonds (1170.79 cm-1). The results of the GC-MS analysis showed that the F2RW4 fraction had 2 main compounds, namely methyl decanoate and 11-methyl octadecenoate. The results of the antibacterial activity test showed that the methanol extract and n-hexane fraction of Padina minor were inactive against the inhibiting bacteria Staphylococcus aureus and Escherichia coli.

Abstract:

The aim of this work is to synthesize and characterise the halogenated derivatives of the endocrine disrupting compounds (EDCs) 4-nonylphenol (4-NP) and bisphenol A (BPA). Characterisation was performed after gas chromatographic (GC) separation on-line coupled to mass spectrometric (MS) detector and a Fourier Transform Infrared (FTIR) spectroscopic detector. Further structure elucidation was done applying Nuclear Magnetic Resonance spectroscopy (NMR). Two different approaches for the preparation of derivatives were evaluated. At first trifluoroacetyl derivatives were synthesized by the reaction of trifluoroacetic acid (TFA) anhydride and the EDCs in acetonitrile at a temperature of 50°C for 30 minutes. In a second step the 4-NP was derivatised using trichloroacetic acid anhydride and triethylamine in diethyl ether at 20¡C for 30 minutes. After synthesis the halogenated NP and BPA derivatives were characterised applying GC/MS, GC/FTIR and NMR. Three indices for a successful derivatisation were observed: EI-GC/MS proved a complete derivatisation presenting a characteristic fragmentation pattern for each derivative. The IR spectra obtained by GC/FTIR after derivatisation and separation confirmed the loss of the phenolic O-H stretching vibration at 3,600 cm-1 while typical absorptions for halogenated compounds now were observed. The NMR-spectra contained the predicted resonance signals.

Abstract:

Medicinal plants are vital to human and community health. This work aimed at using gas chromatography-mass spectrometry (GC-MS) and Fourier transform infrared (FTIR) to determine the phytochemical contents of ethanol leaf extract of <em>Sida acuta</em> from Imo State, Nigeria. Leaves of <em>Sida acuta</em> were collected, washed, air-dried, and pulverized. Pulverized leaves were extracted in 100% ethanol at 70°C in a water bath. Bioactive compounds from the extract were analyzed using Agilent Technologies GC equipment and Buck Scientific M530 USA FTIR. The GC-MS Screening of the plant’s extract revealed the presence of seventy-one (71) phytocompounds including gamma-terpinene (1.11%), p-cymene (0.29%), linalool (2.45%), alpha-cubebene (0.11%), alpha-copaene (1.34%), aromadendrene (6.21%), humulene (1.90%), alpha-selinine, guaiol (0.58%), phytol (0.11%), butyl-2-ethylhexylphthalate (0.32%), 1,2-benzenedicarboxylic acid (0.40%),  1-docosene (0.36%), 1,4-dichlorobenzene (0.22%), (e)-.beta.-farnesene (10.87%), and piperine (0.61%), which are reported to exhibit various biological activities. The FTIR analysis of the plant extract revealed functional groups such as Primary (1°) and Secondary (2°) amines, alkanes, alkenes, alkyl halides, carboxylic acids, allenes, aromatics, aliphatic amines, esters, ethers, phenols, and aldehydes. Cross-referencing the phytocompounds with literature revealed a variety of biological functions, including antibacterial, antifungal, anti-inflammatory, anticancer, antimutagenic, antioxidant, antitumor, and others. It may be concluded that <em>Sida acuta</em> contains bioactive compounds with anti-microbial, anti-inflammatory, anti-oxidant, hepatoprotective, and anti-carcinogenic properties, with (E). beta.-farnesene being the most abundant (10.87%).

Abstract:

A subbitumious coal from Erdos, Inner Mongolia, China, was extracted with isometric carbon disulfide/tetrahydrofuran (CS2/THF) mixed solvent. The components and structure features of CS2/THF soluble factions were analyzed by FTIR and GC/MS. The results show that the total extract yield was 6.6% after five extractions with fresh mixed solvent. And the mass fraction of the first extract was biggest which the 68% amount of the total extracts was. The FTIR spectra of the extracts had abundance functional group information, which can fully indicate that the extracts contain aliphatic compounds, aromatic compounds and heteroatom-containing compounds. Only the first extract can be detected by GC/MS among the five extracts and seven compounds were detected by GC/MS clearly and they are aromatic compounds, in which the three larger relative abundance compounds are retene, 7-butyl-1-hexylnaphthalene and 7-isopropyl-1,1-dimethyl-1,2,3,4-tetrahydro- phenanthrene.

Abstract:

The search for alternative ways to give a second life to materials paved the way for detailed investigation into three silica-polyethylenimine (Si-PEI) materials for the purpose of CO2 adsorption in carbon capture and storage. A solvent extraction procedure was investigated to recover degraded PEIs and silica, and concomitantly, pyrolysis was evaluated to obtain valuable chemicals such as alkylated pyrazines. An array of thermal (TGA, Py-GC-MS), mechanical (rheology), and spectroscopical (ATR-FTIR, 1H-13C-NMR) methods were applied to PEIs extracted with methanol to determine the relevant physico-chemical features of these polymers when subjected to degradation after use in CO2 capture. Proxies of degradation associated with the plausible formation of urea/carbamate moieties were revealed by Py-GC-MS, NMR, and ATR-FTIR. The yield of alkylpyrazines estimated by Py-GC-MS highlighted the potential of exhausted PEIs as possibly valuable materials in other applications.

Abstract:

Biomass energy has attracted widespread attention due to its renewable, storage, huge production and clean and pollution-free advantages. Using Robinia pseudoacacia bark (RPB) as raw material, biogas and bio-oil produced by pyrolysis of RPB were detected and analyzed by TG-DTG, TG-FTIR and PY-GC-MS under the action of nanocatalysis. TG results showed that CH4 and CO flammable gases were produced by pyrolysis. PY-GC-MS results showed that RPB was rapidly pyrolyzed to obtain alcohols, ketones, aldehydes and acids bio-oil. The content of phenolic substances was the highest, accounting for 32.18% of all substances.Nanocatalysis has a certain effect on RPB, accelerating the precipitation of pyrolysis products and improving the over-oxidation of bio-oil. In addition, the extracts of RPB were identified and analyzed by FTIR, NMR, GC-MS and LC-Q-TOF-MS, and more than 100 active ingredients, such as Betaine, Epicathin and β-sitosterol, were detected. Their applications as additive energy in other fields were explored. Therefore, Robinia pseudoacacia bark constitutes a fine biofeedstock for biofuels and biochemicals.

Abstract:

The purpose of this article to review the validation and content of antibiotics using various chromatographic and spectrophotometric methods. This review article used five analytical methods on antibiotics, namely high-performance liquid chromatography (HPLC), Fourier transform infrared (FTIR), gas chromatography (GC), ultraviolet-visible (UV-Vis) spectrophotometer and liquid chromatography/mass spectrophotometer (LC/MS) methods. Antibiotics are the most widely used drugs for infections caused by bacteria. Based on a review of several studies related to antibiotic analysis, the general techniques applied are HPLC, FTIR, GC, UV-Vis Spectrophotometry, and LC-MS. Analysis of this antibiotic is a massive challenge due to its sensitivity and instability to various conditions.

Abstract:

Drug trafficking, the most widespread and profitable form of organized crime globally, continuously evolves to outsmart law enforcement through innovative methods such as concealing drugs in maritime vessels, semi-submersible vessels, small aircraft, drones, hidden vehicle compartments, and commercial shipments. A recent case in Kochchikade, Negombo, Sri Lanka, where 388 plastic potatoes total containing 96.28 kilograms of brown colored powder were confiscated in a consignment from Pakistan, exemplifies these challenges. Initial suspicions led the Police Narcotics Bureau, Sri Lanka to a warehouse inspection, resulting in arrests and ongoing investigations. The detection methods employed included Thin Layer Chromatography (TLC), Gas Chromatography with Mass Spectrometry (GC/MS), Fourier Transform Infrared Spectroscopy (FTIR) for qualitative analysis, and Gas Chromatography with Flame Frame Ionization Detector (GC-FID) for quantitative analysis. As a result, heroin was detected in the brown colored powder by TLC, GC/MS, and FTIR and heroin was quantified using GC-FID. The analysis revealed that 67.76 kil

Abstract:

The composition of the repugnatorial secretion of some populations of the Cuban endemic millipede Rhinocricus inhabiting in the western region of the Cuban archipelago has been developed. Several quinonoids metabolites were identified. From some individuals (males), collected in forest and karst regions, 850 μg of a deep brown-red secretion were obtained, and directly introduced into analytical instrumental (GC-MS and FTIR). The analysis of FTIR and GC-MS spectra shows that major components of secretions are substituted hydroquinones, 1,4-benzoquinones and aldehydes. The biological effects of these defensive secretions were evaluated on pathogenic microorganisms, showing interesting antimicrobial action. The ecological and evolutionary significance of chemical differentiation in millipedes populations require further study.

Abstract:

The composition of catering waste oil is similar to that of traditional materials for the preparation of fatty acid collectors, which makes it possible to change catering waste oil into fatty acid collector applied to ore flotation. The collectors which come from catering waste oil are detected by FTIR and GC-MS analyses. The FTIR date shows that collectors contains lively carboxyl functional groups and The GC-MS date reveals that those carboxyl functional groups exist in single unsaturated fatty acid and three unsaturated fatty acid. The collectors can be applied to iron ore reverse flotation, apatite flotation, and fluorite flotation. It has better flotation experiment results than the traditional collector that using in field production.

Abstract:

The present work is aimed to determine the chemical constituents in Baliospermum montanum methanolic extracts. An in vitro regenerated procedure was developed for the induction of callus from stem explant cultured on Murashige and Skoog (MS) medium fortified with various concentration and permutations of 2, 4-dichloro phenoxy acetic acid, 1-naphthalene acetic acid, 6-benzyl amino purine and gibberellic acid. FTIR &amp; GC-MS analysis was done according to standard procedure. The quantitative estimation of β-sitosterol was done by HPLC method. Maximum fresh and dry weight of callus was estimated in the combination of GA3 (0.5 mg/L) + NAA (2 mg/L) compared to other concentration. The FTIR analysis showed various functional compounds with different characteristic peak values in the extracts. Major bioactive constituents were recognized in the GC-MS analysis. Root extract revealed the existence of 1-hexadecanol, pentanoic acid, 2-(aminooxy)- and 1-hexacosanol. Leaf extract showed the presence of propanoic acid, 2-oxo-, trimethylsilyl ester, 9,12-octadecadienoic acid (z,z)-, trimethylsilyl ester, docosane, 1,22-dibromo- and pentatriacontane. Stem and stem derived callus exhibit the presence of 1,6,3,4-dihydro-2-deoxy-beta-d-lyxo-hexopyranose, n-hexadecanoic acid and pentanoic acid, 2-(aminooxy). The methanolic extract of leaf exhibited 0.2149 % of β-sitosterol content. There were no peaks observed in the root, stem and stem derived callus. Further studies are necessary for the isolation and characterization of bioactive compounds from B. montanum.

Abstract:

Ethyl carbamate (EC, urethane, C2H5OCONH2) is a genotoxic carcinogen and is regularly found in fermented food products including alcoholic beverages. In this study, the rapid method of nuclear magnetic resonance (NMR) spectroscopy in combination with partial least squares (PLS) regression is applied for the first time to the analysis of ethyl carbamate in stone fruit spirits () and unrecorded alcohols () (analysis time only 15 min per sample). The PLS procedure was validated using an independent set of samples (, , mg/L) in comparison to reference GC/MS/MS results. The NMR method was found to outperform other screening techniques based on NIR or FTIR regarding sensitivity and selectivity. The major advantage over GC/MS/MS, besides the reduced time of instrumental analysis, is that no sample preparation besides addition of buffer with internal standard is required, while for GC/MS/MS labour-intensive sample extraction is necessary prior to measurement.
