Analytical Trap Comparison for USEPA Method 8260C
Purge and trap concentration is a technique that is used for the analysis of Volatile Organic Compounds (VOCs). The major component of any purge and trap system is the analytical trap. This trap is responsible for retaining the VOCs during the purge cycle and then releasing them upon heating and transfer to the GC/MS for separation and detection.
While most standard methods define the dimensions of the trap as well as the recommended packing materials, there are multiple packing choices that can be substituted as long as they meet the analytical requirements of the method. For this study, four analytical traps commonly used for purge and trap analysis will be compared using an automated VOC sample prep system. Linear calibrations and Method Detection Limits (MDLs) will be established for US EPA Method 8260C1 compounds for each trap.
