Purge & Trap
Purge & Trap is used for the analysis of volatile aromatic and halogenated hydrocarbons. In short, the principle of Purge & Trap is to pass an inert, pure gas through a (heated) closed purging vessel whereby the volatile hydrocarbons are driven from the sample. The expelled volatile hydrocarbons are transported with the gas to the trap (an absorbing agent). This trap can be packed with various materials; a well-known example is VOCARB 3000. After absorption, the trap is heated and the components are transported to the capillary column in the GC. In the GC, the components are separated and detected. JSB has several options for the analysis of volatile hydrocarbons.
