Packed Columns Ordering Guide
Caution When Using Columns
- When analysis or conditioning the column, do not set the oven temperature exceeding the maximum temperature. It may induce the column deterioration.
- Purge the packed column with enough carrier gas before start heating. Use inert- gas for carrier gas in analysis such as Nitrogen (N2), Helium (He), Argon (Ar), which are purer than 99.99 %.
- Especially Polyester or Polyethylene glycol type packing materials are easily oxidized by air. If the column still contains air and the temperature is increased, it may cause damage and a deterioration of the column performance. (Ex. purge the column with carrier gas at least 1 hour, then raise the temperature with 1 °C / min. rate)
- When conditioning, do not connect the outlet of the column to the detector. It may contaminate the detector with eluted liquid phase from the column.
