Thermodynamic Studies on Poly(n-butyl methacrylate)—Solute Systems Using Gas Chromatography

Determination of Solubility Parameters and Thermodynamic Properties in Hydrocarbon-solvent Systems by Gas Chromatography

Gas chromatography used to calculate the specific retention volume of several hydrocarbons in different chromatographic liquid phases (Squalane, Carbowax-400, Carbowax-1500, Carbowax-4000, Amine220, Dinonyl phthalate, Tributyl phosphate and Trixylenyl phosphate). Some thermodynamic parameters, such as enthalpy of sorption and Flory-Huggins parameters relating the interaction between liquid phas...

Designing Novel Functional Food Using Gas Chromatography

Determination of 3,6-dichloropicolinic acid residues in soil by gas chromatography of the 1-butyl ester.

Since 3,6-dichloropicolinic acid is simil8r to picloram, the method developed previously for picloram by McKone and Cotterill (1974) was examinedo This method~ like that of Pik and Hodgson, uses diazomethane for methylationo However~ the methyl ester of 3 87 acid is sufficiently volatile for losses fo occur during the final concentration stepo This report shows how tbe difficulty tan be overcom...

Thermodynamic Performance Assessment of Steam-Injection Gas-Turbine Systems

The cycles of the steam-injection gas-turbine systems are studied. The analyses of the parametric effects and the optimal operating conditions for the steam-injection gas-turbine (STIG) system and the regenerative steam-injection gas-turbine (RSTIG) system are investigated to ensure the maximum performance. Using the analytic model, the performance parameters of the system such as thermal effic...

Gas chromatography-mass spectrometric studies of canine urinary metabolism.

After the urine was treated with urease, lyophilized, and trimethylsilylated, it was examined for metabolic profiles in Dalmatian dogs and Shetland sheepdogs by gas chromatography-mass spectrometry (GC/MS), which simultaneously analyzes organic acids, amino acids, sugars, sugar alcohols, purine and pyrimidine bases, and nucleosides. The profiles were compared with those from human specimens. As...
