Originally headspace analysis was only carried out with crimp neck vials due to the temperature reistance of the caps (aluminum with an appropriate septa type) and the gas tightness being expected by endusers to be the highest. However, with the success story of the CTC Combi PAL and identically constructed autosamplers that require magnetic caps for transportation, consumables startet to change.
