一般描述
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℃. Glass column are in some cases treated with silanizing reagent to eliminate the surface hydroxyl groups which becomes catalytically active and produce asymmetric peaks.
Use a glass column for applications where high inertness is required, such as for the analysis of active analytes. All glass columns undergo a proprietary high temperature silanization to ensure inertness. This column fits Agilent 5880, 5890, 6890. 7820, and 7890 (configuration A, on-column injection, all detectors except TCD).
其他说明
This is a TightSpec column, which conforms to within +/- 6 mm of its stated length.
