SilTite metal ferrules have been developed specifically for use with GC/MS systems and have distinct advantages over graphite and composite ferrules for use with GC/MS interfaces. SilTite ferrules form a strong permanent airtight seal around the capillary column. The metal SilTite ferrule and nut are made from the same material and therefore have the same thermal expansion coefficient. As the oven heats up and cools down, the nuts and ferrules expand and contract at the same rate, eliminating annoying leaks and the need to retighten the ferrule after installation.
The base of the SilTite ferrule is flat and forms a perfect seal with the MS interface, covering the whole transfer interface. SilTite nuts are reusable. and are easily removed from the specially designed nut while still attached to the capillary column. SilTite metal ferrules have a temperature tolerance well above the limit of the injector, MS interface or GC oven. Removes contamination caused by Vespel or graphite ferrules, and reduced air background gives a cleaner spectra with better library matches.
