Heated Adsorbent Traps

Dual setpoints for adsorption & desorption temperatures Preconcentrates molecules between C3 and C15 Single or dual independently heated traps Requires a 10 port valve & valve oven Adsorbent packing of your choice PeakSimple control ADSORBENTS: Carbosieve II MoleSieve 13X Carbopack B Silica Gel HayeSep-D Tenax-GR Heated adsorbent traps are a simple and economical way to preconcentrate samples for the GC. A heated trap consists of a stainless steel tube packed with adsorbent. While sample is drawn through the tube, analytes of interest are trapped on the adsorbent bed. Then, the trap is heated and the valve rotated to desorb the analytes into the carrier gas stream, which deposits them in the analytical column for separation prior to reaching the detector. Each trap is plumbed as a sample loop of a 10-port gas sampling valve. A valve and heated valve oven must be ordered along with a heated trap. Heated traps are installed in the ducts of the valve oven on the left-hand sid
