色谱科气相色谱玻璃空柱：

Silane treated empty glass column. Fittings are not included.
* X (length of injector arm) = 8.62 in. (219 mm)
* Y (length of detector arm) = 8.62 in. (219 mm)
* S (span, injector to detector) = 8.75 in. (222 mm)
This column fits PerkinElmer 115, 300, 900, 2000, and Sigma (not 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.
