How do you condition Molecular Sieve 5A, Product 20302, when used in a packed column?
Attach the column to your GC injection port, establish a flow rate of at least 25 mL/min carrier gas, purge with carrier gas at room temperature for 30 minutes, increase oven temperature to 225°C at a rate of 4°C/min, and allow the column to condition at 225°C for 8-12 hours. After conditioning, allow the oven to cool to room temperature, turn off the carrier flow and allow the pressure to go to zero. Then reinstall the column into both the injector port and detector port, and establish desired carrier flow rate. The column should then be ready to use.
