This document provides a user guide for Varian Packed GC Column, including instructions for preconditioning, gas purification, and optimum flow.
The document outlines a procedure for preconditioning Varian packed GC columns. It specifies heating temperatures relative to the maximum operating temperature (20 °C below) and provides ramp rates from 30 °C to 300 °C at 0.5 °C/min depending on column dimensions.
Additionally, the guide emphasizes the importance of using purified carrier gas with a minimum flow of 20 mL/min. It lists specific Varian Gas Clean filters (Oxygen, Moisture, Charcoal, and GC/MS) designed to prevent contamination that could cause damage or loss of sensitivity.
The column should be heated to 20 °C below its maximum operating temperature.
