General description

Silane treated empty glass column. Fittings are not included.
* X (length of injector arm) = 11.02 in. (280 mm)
* Y (length of detector arm) = 9.05 in. (230 mm)
* S (span, injector to detector) = 9.0 in. (229 mm)
This column fits Agilent 5880, 5890, 6890, 7820, and 7890 (configuration A, on-column injection, all detectors except TCD).

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.
