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.

To get reliable analysis data, the sealing process of the sample vials needs to be reproducible. This is difficult to achieve with manual crimpers. Learn more about our range of electronic crimping tools that solve inconsistencies in crimp results.

Robotic sample preparation lines as well as some autosamplers are constructed that way that they lift and transport vials with a magnet the size of the vial’s cap. In these cases aluminum crimp or plastic screw caps cannot be used, as these materials won’t react to a magnet. Only metals like steel or tin will do so, however, they will also bear some problems that need to be considered.
