Volatile Organic Compounds (VOC)
In the 1960’s, Purge and Trap (P&T) was used in the study of bodily fluids. In the mid-to-late 1970’s, P&T became a technique that was well-known and widely applied due the need to monitor VOCs in drinking water. Using this technique, it was possible to detect sup-ppb level VOCs of a wide variety. Today, P&T is routinely applied in the environmental area for the analysis of VOCs in soil and water. The arrival of microprocessor-driven systems allows the concentrator to be more precise and automated, giving the operator more time for other projects.
When using a concentrator system, a good grasp of the fundamentals will help you prevent problems and assist you when you are faced with tasks such as method development and troubleshooting.
