A quadratic programming routine for the statistical analysis of gas chromatographic data

Creator:: Elliott, Stanley Claud, Jr
Abstract:: A quadratic programming method was developed for the statistical analysis of gas chromatographic data. The method was applied to three types of flavor extracts, peppermint, hops and brewed tea. The brewed tea data had to be abandoned because of the singularity of its coveriance matrix. In all cases tried the...

Gas chromatographic determination of selenium in biological materials

Creator:: Pedersen, Nels David
Abstract:: A method for the determination of selenium in biological materials by gas-liquid chromatography has been developed and successfully applied to kidney, heart, liver, and muscle tissue. The initial digestion of animal tissue was accomplished in a mixture of nitric and perchloric acids (3:1) until "water whiteness'' of solution was achieved....

Diffusion in silicone polymers

Creator:: Kong, Ming J.
Abstract:: The study of diffusion coefficients of n-alkanes and other organic compounds in silicones is undertaken by gas-liquid chromatography. About 0. 3% of stationary phase is coated on glass bead support so that the only significant source of peak spreading is due to slow liquid phase mass transfer. Diffusion coefficients are...

Diffusion of n-alkanes in polydimethylsilicones

Creator:: Millen, William George
Abstract:: Diffusion of short chain n-alkanes was found to be faster in the polydimethylsilicone elastomer SE-30 than in the polydimethylsilicone oil SF-96-2000. The opposite was true for the longer chain n-alkanes suggesting that choice of stationary phase for gas chromatography would depend on the chain length of sample components. The dependence...

Slow processes in gas-solid chromatography

Creator:: Burns, Walter Frederick
Abstract:: Gas-solid chromatography often has asymmetrical elution peaks. This is attributed to nonlinear isotherms, multi-energy adsorption sites, and slow processes. This study utilized a stopflow gas chromatograph with various NaOH and NaCl modified aluminas as adsorbents and methane as adsorbate to determine the influence of surface area and pore volume distribution...

Classification of stationary liquids in gas chromatography by infrared spectrophotometry

Creator:: De Briceno, Maria Betania Orduz
Abstract:: A classification of stationary liquids by infrared spectroscopy to evaluate the polarity was made using the solvent effect technique. The infrared C-Cl absorption frequency shift was measured for solutions of 1-chlorohexane dissolved in each stationary phase. These frequency shifts were correlated to the relative retention times of 1-octene/n-octane, trans-2-octene/n-octane and...
