MilliporeSigma™ Supelco™ Glass Packed GC Column (fits Agilent, Configuration A), Phase: 3 OV-101, Matrix 100/120 Chromosorb W HP Support

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 700C
• Glass column are in some cases treated with silanizing reagent to eliminate the surface hydroxyl groups which becomes catalytically active and produce asymmetric peaks
• Chromosorb W is a fragile white solid prepared by heating the diatomaceous earth with a flux
• The resulting fine structure is then cemented over glass which results in large and irregular pores
• HP is the classification of a support as high performance grade.
