Glass Packed GC Column (fits Agilent, Configuration "A"), 1 X 1 ea (23110-U)

In a packed column, the carrier gas percolates through the porous bed and separation is achieved by moving the solutes apart. Packed columns are made up of two main materials; stainless steel and Pyrex glass. Pyrex glass columns are shaped as desired by coiling at about 700°C. Glass column are in some cases treated with silanizing reagent to eliminate the surface hydroxyl groups which becomes catalytically active and produce asymmetric peaks. This is a TightSpec column, which conforms to within +/- 6 mm of its stated length.
