Saudi Arabia standard neck headspace gas chromatography with high quality

2014/7/15 · Sample is derivatized in-situ directly in a headspace sampling vial prior to vapor phase extraction and injection into a gas chromatograph. The chemistry of the derivatization is unique to the detection of the molecules of ethylene glycol and 1,2- propylene glycol. 1,3-propylene glycol could also be detected but is not used in any known anti-freeze at this time.

endogenous ethanol concentrations in blood were determined by sensitive headspace gas chromatography/mass Spectrophotometry in 1400 residents of Saudi Arabia. The subjects were from 14 nationalities, of both sexes and of different age groups. There was

The determination of residual solvents (organic volatile impurities) by GC headspace is an important quality control procedure in the pharmaceutical industry. Residual solvent testing is defined in accordance with the ICH 1 and required by USP and Ph. Eur. ICH guidelines include maximum concentration limits for Class 1, Class 2, and Class 3 residual solvents (most to least toxic, respectively).

Headspace sampling allows the introduction of volatile compounds, from virtually any matrix, directly into a GC or GC/MS instrument. According to Aijiren, the technique is relatively simple when compared to other injection techniques such as purge and trap, and keeps instruments cleaner than the standard
