Determination of hydrocarbons in water by using flame ionization detector

Determination of 2-phenylethanol in Rose Water Using Dispersive Liquid-Liquid Microextraction with Gas Chromatography Flame Ionization Detection

A simple and rapid microextraction procedure based on dispersive liquid-liquid microextraction (DLLME) coupled with gas chromatography-flame ionization detection (GC-FID) was developed for the extraction and analysis of 2-phenylethanol in rose water sample. In the proposed approach, carbon tetrachloride and ethanol were used as extraction and dispersive solvents, respectively. Some important pa...

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

Aspects of the mechanism of the flame ionization detector

The development of flame ionization detection took place on an empirical basis without a clear understanding of the 1 mechanism. The study of flames by mass spectrometry showed that the all-important ion was the formylium ion CHO . The pre-combustion degradation was thought to be a pyrolytic degradation and hydrogenation at the high temperatures obtained close to the combustion zone. Using a ca...
