In this field, solid-phase micro-extraction (SPME) in the headspace mode (HS), coupled with gas chromatography–mass spectrometry (GC–MS), is known to provide a «chemical signature

A gas chromatographic method for the rapid determination of aqueous carbon dioxide and its speciation into solvated carbon dioxide and bicarbonate is presented. One-half mL samples are injected through a rubber septum into 20-mL vials that are filled with 9.5 mL of 0.1 N HCl. A one mL portion of the headspace is withdrawn and injected onto a gas chromatograph equipped with a thermal

The optional barcode reader enables samples to be controlled via a chromatography data system. Sample Concentration The HS-20 trap model is equipped with an electronic cooling trap that concentrates the headspace gas, enabling high-sensitivity analysis.
