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.
Silane treated empty glass column. Fittings are not included.
X (length of injector arm) = 9.25 in. (235 mm)
Y (length of detector arm) = 2.0 in. (51 mm)
S (span, injector to detector) = n/a
This column fits Varian 3000, 4000, 6000, and Vista (on-column injection). The three piece construction (injector arm + coil, union, and detector arm) allows its use in any injector to detector position (A to A, B to B, A to B, and B to A).
Empty column may be used for packing adsorbents for temperature-programmed desorption (TPD) instrumentation.
