Online Sampler/Sparger for HRVOC GC

Online Sampler/Sparger for HRVOC GC


  • Allows testing of cooling tower water with the HRVOC GC
  • Collects dissolved gases from sample liquids
  • Sweeps dissolved gases into Peltier traps

The Online Sampler/Sparger is designed for use with the HRVOC GC system. It allows online sampling of cooling tower water and other liquids. The peristaltic pump draws sample liquid through silicone tubing in the test tube. HRVOCs like ethylene, propylene, 1,3-butadiene, butenes, etc. permeate through the silicone tubing and are then swept by the purge gas into the sample dryer, then into the CryoCooled Peltier Trap Accessory (both included with the HRVOC GC system), where they are concentrated on the Carbopack X and Molecular Sieve 5A traps prior to desorption and separation by the analytical column.
