common use headspace gas chromatography with round bottom Sigma

This paper describes the use of headspace solid-phase microextraction (SPME) combined with gas chromatography to identify the signature odors that law enforcement-certified detector dogs alert to when searching for drugs, explosives, and humans. Background information is provided on the many types of detector dog available and specific samples highlighted in this paper are the drugs cocaine

A gas chromatography (GC) headspace technique was applied to analyze SMM and DMSO in malt. Nitrogen-purging was used to remove free DMS from the malt extract, therefore only SMM was determined

Briefly, 1 g FeCl 2 ·4H 2 O and 2.6 g FeCl 3 ·6H 2 O were dissolved in 12.5 mL purified water and 0.4 mL hydrochloric acid (12 mol/L), then the mixture was added into round bottom flask containing 125 mL NaOH (1.5 mol/L) and 1 mL oleic acid with nitrogen gas

CHS vial is intended to be used with the most common headspace autosamplers worldwide, DANI – with models Master, HSS8650, and their OEM version under the code anad E. Because CHS vial has got rounded bottom, it is compatible with other headspace autosamplers, eg.
