General description
Packed column percolates the carrier gas through the porous bed. In a packed column, separation is achieved by moving the solutes apart. Packed columns are made up of two main materials; stainless steel and Pyrex glass. Metal packed columns are more suitable for long and high carrier gas flow rates to tolerate the elevated pressures. 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.
