20ml headspace gas chromatography with high quality

Headspace-Gas Chromatographic-mass spectrometry (HS-GC-MS) analysis Headspace Procedure The samples were placed in 20 mL headspace vials by adding 1 mL of samples, standards or quality control samples and 0.5mL of internal StandardTable 1.

The 20ml headspace vial is very popular in gas chromatography because of its large capacity, because it allows the vaporized gas in the sample to float on the upper layer and completely separate from the liquid, which is convenient for the autosampler to extract

2020/3/20 · Headspace gas chromatography is composed of a gas chromatograph (Aijiren A) connected with a headspace sampler (COLIN AutoHS®). The GC analysis equipped with GS-Q capillary column (0.53 mm × 30 m × 0.2 m, Aijiren) and a TCD detector.

2011/2/1 · For the analysis of residual solvents, gas chromatography in combination with flame ionization detection (GC-FID) is normally used. Sample preparation and introduction is via static headspace (SHS). 2,3 In this way, the (mostly) volatile solvents are introduced selectively, and the analytical system (inlet, column, and detector) is not contaminated by the (mostly) nonvolatile

2003/1/1 · As a result, static headspace is suitable for the analysis of samples with high contents of volatiles . Solid-phase microextraction (SPME) is the newest approach in the analysis of volatiles. This technique has been successfully applied to the analysis of THMs [14] , aldehydes [15] , geosmin and MIB [16] , BTEX [17] , [18] , organochlorine pesticides [19] and PAHs [20] , [21] .
