Big Traps

Big Traps from Agilent

The purpose of gas traps is to remove detrimental impurities from carrier and detector gases. 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.
