1994/4/29 · Solvents are best analyzed by gas chromatography [1-4]. Direct injection, purge-and-trap and headspace injections are common ways of introducing the sample in GC. Direct injection of a solution of a non-volatile drug substance could be detrimental to the performance of the injection system of the gas chromatograph and also to high-performance capillary columns.

2007/8/15 · The extraction was performed in headspace mode in a 20-mL headspace vial that contained 10 mL of water sample as illustrated in Fig. 1. The HAAs in water sample were in situ derivatized with acidic/methanol by first adjusting the pH to less than 0.5 with 1 mL 98% sulfuric acid, and then the methanol was pipetted into the sample after the solution was cooled down.
