Abstract:

Introduction Oligonucleotides are short nucleic acid chains, usually 19-27mer long. They bind to their corresponding chain, making a specific inhibition possible. In pharmaceuticals, this can be used to inhibit the expression of a gene or protein of interest. Oligonucleotides are usually analyzed based on separation using both hydrophobic and ion-exchange properties. In this project, the possibility to use a mixed-mode column to separate these oligonucleotides and their impurities were explored. Method Liquid chromatography is used as the separation method and the method of detection is both m

Abstract:

Manganese is a crucial element in the manufacturing of steel, which in turn is an essential material in many industries including construction and transportation. Its use in the steel making process results in increased strength and resistance. Manganese samples are analyzed quantitatively by volumetric titration techniques. These wet chemistry methods are simple, accurate, and are sufficiently detailed for ordinary personnel to follow with ease. The research method used included the investigation of using secondary standard created from the current mining activities to match the matrix

Abstract:

“Green” explosives are an important sub-family of explosives due to the banning of explosives based on heavy metals, such as lead azide and lead styphnate, according to the REACH list. A substitute to lead azide is potassium 4,6-dinitrobenzofuroxane (KDNBF) which is an alternative “green” explosive. Hence there is an upcoming need for analytical and quality control protocols for KDNBF. In this report is HPLC-UV/VIS, GC-FID and potentiometric titration evaluated for their suitability as methods for testing of KDNBF. The results implies that KDNBF can be analyzed by GC-FID, when dissolved in DMS

Cereals are rich in phenolic acids, a group of secondary plant metabolites that are associated with reduced risk of chronic diseases. The objective was to develop and internally validate a method for extraction and quantification of phenolic acids in cereals using HPLC-UV and to apply this method for quantification of the content of phenolic acids in several species of Swedish cereals. Different procedures for extraction of phenolic acids from cereal grains using acid or base hydrolysis with and without subsequent enzymatic treatment were tested.

<p>The objective of this master thesis was to develop an analytical method for the quantification of the cancer drug Imatinib and its main metabolite CGP74588 in plasma. Imatinib is used in the treatment of chronic myeloid leukemia and gastrointestinal stroma tumors. A quantitative analytical method was developed where reversed-phase columns with different stationary phases were studied and the sensitivity was tested with both UV detectors and a mass spectrometric detection. Since the substances were measured in plasma a solid-phase extraction was developed to purify the samples before analysi

Investigation in food science and technology, both by the food industry and governmental agencies, is based on the evaluation of food composition and characteristics. All food products require analysis as part of a quality management program that involves the development, the production processes and the control of the commercial product. The chemical composition and physical properties of food are necessary to evaluate the nutritive value, the functional characteristics and the acceptability of the food product. The nature of the sample and the specific use of the analysis dictate the choice

Abstract:

Analysis of the molecular speciation of organic compounds in solution is essential for the understanding of ionic complexation. The Raman spectroscopic technique was chosen for this purpose because it allows the identification of compounds in different states and it can give information about the molecular geometry from the analysis of the vibrational spectra. In this research the ionisation steps of relevant pharmaceutical material have been studied by means of potentiometry coupled with Raman spectroscopy; the protonation and deprotonation behaviour of the molecules were studied in different
