Abstract:

An improved spectrophotometric method of determining equilibrium constants is introduced. The advantages offered by photodiode array spectrophotometer are exploited. The most important of these are the ability to precisely measure analyte absorbance at all wavelengths throughout the ultraviolet and visible spectral range and store the data in computer files. A spreadsheet program is used to assemble the spectral data into an organized array and calculate the most probable value of the equilibrium constant for the entire array. Linear least-squares analysis and weighting scheme are employed to

Abstract:

Antibiotic resistance is one of the most serious medical problems in the world. To counteract the increase in antibiotic resistance, new rapid and effective analytical methods are needed. To effectively treat infections in critically ill patients, optimal antibiotic dosages are required. DrugLog® is an instrument that uses a spectrophotometric method to analyze antibiotics in plasma in the wavelength range 200-800 nm. The aim of this study was to do a method validation of the instrument DrugLog®. The study material that was used was whole blood from healthy donor and routine citrate plasma

\"Maracujá\" é o nome popular de várias espécies, dentre as quais Passiflora edulis e Passiflora alata (Passifloraceae). Esta última é uma planta medicinal amplamente utilizada no Brasil devido às suas propriedades ansiolíticas e sedativas, sendo também a espécie oficial da Farmacopéia Brasileira. Porém, freqüentemente ocorre a sua substituição indevida por Passiflora edulis, espécie usada para o preparo de sucos. Há também a confusão com a Passiflora incarnata, espécie usada na Europa, mas que não se adapta bem ao clima brasileiro. Neste trabalho foi desenvolvido um método espectrofotométrico

Abstract:

The uptake of anthropogenic CO2 by the oceans since the onset of the industrial revolution is considered to be a serious challenge to marine ecosystems due to ensuing carbonate chemistry changes (ocean acidification). Furthermore, the CO2 uptake is reducing the ocean’s capacity to absorb future CO2 emissions. In order to follow the changes in the ocean’s carbonate system, high-quality analytical measurements with good spatial and temporal resolution are necessary. The spectrophotometric pH technique is now widely used and capable of the required high-quality measurements. Smaller and more rugg

The spectra of these white dwarfs are analyzed in order to generate a non-local-thermodynamic-equilibrium model atmosphere normalized to Hubble Space Telescope colors, including adjustments for wavelength-dependent interstellar extinction. Once established, this standard star

Abstract:

Although chemists often exploit the high stereo selectivity of hydrolytic enzymes to produce pure enantiomers, the difficulty in selecting the best hydrolase from hundreds of commercial hydrolases and microorganisms remains a major deterrent to their wider use. Moreover, the emerging ability to create large libraries of recombinant enzymes demands fast and simple selection methods. The current method of selection is time-consuming because it requires carrying out small-scale reactions and measuring enantiomeric purity.

In this study, a reproducible spectrophotometric method was established and applied to measure reductive capacity of various nanomaterials. Reductive capacity had been implicated in the toxicity of nanomaterials, but a standardized measurement method had been lacking until this work. The reductive capacity of nanoparticles was defined as the mass of iron reduced from Fe3 to Fe2 by unit mass of nanoparticles, in an aqueous solution that initially contained ferric ions. To measure the reductive capacity, the nanomaterials were incubated in a ferric aqueous solution for 16 hours at 37 degrees C

碩士<br>淡江大學<br>水資源及環境工程學系<br>90<br>Ⅰ. A Study for the Determination of Organochlorine Pesticides in Waters by the Solid Phase Microextraction/Gas Chromatography (SPME-GC). The traditional extraction method (liquid-liquid extraction and solid phase extraction) was used as pretreatment in the determination of the organochlorine pesticides in water. The analytical method consisted of water removal, condensation, clean-up, rinsing, fractional distilltion for liquid-liquid extraction and filtering, elution for solid phase extraction followed by gas chromatography detection. The whole
