General description
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. Carbopack B, better known as graphitized carbon black has nonporous, nonpolar and homogeneous surface. This adsorbent is suitable as stationary phase in both packed and capillary columns. Carbopack B cartridges are more efficient than C-18 for extracting phenols.
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).
Application
Carbopack B packed glass column was used in GC analysis of C2-C5 fatty acids in aqueous media.
Other Notes
This is a TightSpec column, which conforms to within +/- 6 mm of its stated length.
