Agilent CrossLab Supplies for Bruker, Varian GC Systems - Column Ferrules
By Agilent TechnologiesA variety of column ferrules are available to meet your application requirements, including 100% Graphite, 100% Vespel and Vespel/Graphite ferrules.
Using the wrong ferrule or a worn-out ferrule to seal your column connection can result in inconsistent and unreliable chromatography. An improper ferrule can cause leaks, which allow air and other contaminants to enter the instrument through the column seal, causing major interference with column and detector performance.
The ideal ferrule provides a leak-free seal, accommodates various column outer diameters, seals with minimum torque, withstands temperature cycling, and does not stick to the column or fittings. For optimum performance, ferrules should be replaced every time the column is replaced and when performing column maintenance.
