The United States Pharmacopeia (USP) and ASTM have developed methods for identifying residual solvents with the use of a headspace (HS) extraction alongside a Gas Chromatograph (GC) with a Flame Ionisation Detector ...
Environmental Protection Agency (EPA) has developed a standard method, namely EPA 524.3 to identify and quantify the purgeable organic compounds in finished drinking water by using purge-and-trap with GC-MS. Headspace with trap mode could serve as an alternative option in analysing the purgeable VOCs. During incubation, VOCs from water samples are effectively partitioned into ...
The headspace solid-phase micro-extraction (HS-SPME) method with polydimethylsiloxane (PDMS, 100 μm) fiber is a cost-effective technique for the determination of different pesticide residues in environmental and biological samples followed by a gas chromatography-electron-capture detector (GC-ECD). ...
EPA method 5030 is a purge-and-trap technique for the analysis of high concentration VOCs in soils using methanol(MeOH) extracts. EPA method 5021 is a general purpose method for the determination of VOCs in soils using equilibrium headspace. ...
