New 9mm Ms-cap Without Septa

of chromatography as the purest available liner material. However, still most of the end-users experienced problems with even the highest grades of Silicone/PTFE septa due to ghost peaks arising from volatile siloxanes. Of course different treatments can reduce the level of these volatiles, but not eliminate the basic problem. La-Pha-Pack now has therefore developed a one component 9mm Short Thread Cap that doesnât require any septa. This cap is inert and shows a similar chemical resistance like PTFE. Thus it can be used for sealing vials with all kinds of samples without loosing its inertness.
Furthermore the cap is made out of a special material that is pierceable with all common types of HPLC and GC needles, as it has a thinned penetration area with a diaphragm. Although it has no septa,
evaporation tests have shown that it is liquid and gas-tight. Each manufactured batch is LC/MS and GC/MS controlled and supplied with an appropriate certificate. The certificate clearly states instrument,
column and other method conditions being used for the test.
