General description

Silane treated empty glass column. Fittings are not included.
* X (length of injector arm) = 9.31 in. (236 mm)
* Y (length of detector arm) = 8.0 in. (203 mm)
* S (span, injector to detector) = 5.5 in. (140 mm)
This column fits Varian 3000, 4000, 6000, and Vista (FID, injector A to detector A, on-column injection).

GC columns are of two types; packed column and capillary column. Capillary column carries the gas through a central aperture which is unimpeded through the entire length of column. In general, capillary columns are made longer to produce more theoretical plates. This also helps in band dispersion eventually narrowing the peaks and resulting in high resolution.
