Headspace Sampling for GC – The Basics. Headspace sampling is a type of sample introduction technique for gas chromatography (GC) and gas chromatography-mass spectrometry (GC/MS). For headspace techniques, the gas layer, or the headspace above the sample in a vial, is analyzed as opposed to withdrawing a volume from within the sample layer
Headspace Vials National Scientific Clear glass vials with 20mm crimp seal finish are designed to fit most headspace autosamplers Flat bottom vials maximize heating efficiency when used with bottom Round bottom vials are more easily handled by robotic arms that lift the vial from the tray Round bottom vials distribute the
1. 20mm crimp headspace vial is widely used in Headspace and GC, GCMS application. 2. 20mm Aluminum Crimp Cap Seals and Vials ensure that a proper seal is made for this demanding application. 3. Vials are manufactured of borosilicate glass and include a write-in patch for sample identification. 4.
