Gas Purification Systems
The purpose of gas traps is to remove detrimental impurities from the carrier and detector
gases. Combination traps are available which remove moisture, oxygen and/or organics
with a single trap. The effectiveness of the traps depends on the initial quality of the gas.
Constant exposure of capillary columns to oxygen and moisture, especially at high
temperatures, results in rapid and severe column damage. The use of oxygen and moisture
traps for the carrier gas may extend column life and protect the instrument. Any moisture
or oxygen introduced into the gas stream due to a leak will be removed by the trap
until it expires.
