Metal Packed GC Column (General Configuration)

Descrição detalhada : In packed columns 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. Metal packed columns are more suitable for long and high carrier gas flow rates to tolerate the elevated pressures.† Chromosorb W is a fragile white solid which is prepared by heating diatomaceous earth with a flux. The resulting fine structure is cemented over glass which results in large and irregular pores.† HP is the classification of a support as high performance grade.†, An economical metal column should be used for less demanding applications where the inertness of glass is not required. This column is of a general configuration, and can be carefully bent to fit most instruments.
