Headspace Gas ChromatographyFlame Ionization Detector Method for Organic Solvent Residue Analysis in Dietary Supplements

Residual solvent determination by head space gas chromatography with flame ionization detector in omeprazole API

Residual solvents in pharmaceutical samples are monitored using gas chromatography with head space. Based on good manufacturing practices, measuring residual solvents is mandatory for the release testing of all active pharmaceutical ingredients (API). The analysis of residual organic solvents (methanol, acetone, cyclohexane, dichloromethane, toluene) in Omeprazole, an active pharmaceutical ingr...

Determination of Triethylamine, Pyridine and Dimethyl Formamide Content in Telmisartan by Headspace Gas Chromatography Using Flame Ionization Detector

A surface ionization detector for capillary gas chromatography.

A novel surface ionization detector using a reducing quartz liner and a Mo emitter with a quartz enclosed internal heater for selective measurement of alkylamines by gas chromatography is designed and evaluated.

development of a new polarographic validated method for analysis of anabolic steroids in dietary supplements

Analysis of Dissolved Gases by Headspace Sampling Gas Chromatography With Column and Detector Switching. Preliminary Results

This preliminary study presents a new method for the determination of dissolved gases in sea-water. After headspace extraction, gaseous compounds are separated by GC on a dual column adsorption system. The individual species are thereafter eluted to three different detectors (thermal conductivity, flame ionization and FPD) using a second switching valve. The analysis is quantitative for methane...
