Thermal Desorption Instrumentation - Sorbent Tube Analysis
There are two types of sampling with sorbent tubes – pumped and passive. Using pumped sampling, air is pulled through a sorbent tube using a pump. Single-bed or multi-bed tubes can be used. A constant flow of gas into the vessel aids release of analytes onto a sorbent tube. Typical analytes monitored by this method are in the range C3 to C44. Sampling is quick (minutes to hours) and a wide range can be monitored in one run. The technique is ideal for all types of ambient air monitoring. With passive sampling, analytes migrate across an air gap onto a bed of sorbent. Here, only single-bed tubes can be used. Typical analytes monitored are also in the range C3 to C44. Passive sampling is easy to deploy but is relatively slow. The technique is commonly used for factory fenceline monitoring and personal monitoring.
