Increase column lifetime because oxygen cannot permeate into the carrier gas Reduced noise benefits high-sensitivity detectors (ECDs or MSDs) Special grade of stainless steel that is softer and deforms more easily, creating a better seal Gold-plated seals offer better inertness than standard stainless steel Siltek™ seals feature inertness similar to that of fused silica capillary columns All seals include washers 1.2mm inlet seal is recommended for use with Vespel™/graphite ferrules or when installing two columns using a two-hole ferrule 0.8mm inlet seal is recommended for use with graphite ferrules and single capillary column installation
