Headspace analysis Chemistry LibreTexts

In an automated system the sample vial is heated during a fixed period of time. After that the sample vial is pressurized. By switching the valve the headspace vapour flows to the sample loop and injection takes place by switching the 6-port valve again. Injection can be direct (wide-bore columns only) or split.

Extractables and leachables analysis of pharmaceutical

Direct injection gas chromatography mass spectrometry (GC-MS) analysis permits analysis of both volatile and semi-volatile leachable species. Head-space GC-MS analysis is an option where a great deal of volatile species may be expected. Elemental impurities are analysed and quantified by inductively coupled plasma mass spectrometry (ICP-MS).
