• allows testing of cooling tower water with the HRVOC GC
• purges dissolved gases from sample liquids onto user's trap-equipped GC
• permits continuous, repetitive purge and trap sampling of a liquid stream or process

The Online Sampler/Sparger is designed for use with the automated purge and trap concentrator, as well as 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 GC system (into the purge and trap concentrator inlet, in place of the standard sparge head, or into the sample dryer, then into the trap accessory mounted on 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.
