Desorption Efficiency Tubes for VOC Chek Passive Sampler 575-001; 10/pk

Desorption Efficiency (DE) tubes contain the same sorbent, and mass of sorbent, as found in their associated VOC Chek 575- Passive Sampler. The sorbent in these tubes is spiked and analyzed by the lab to calculate the desorption efficiency of the sorbent. The DE is used in the final calculation of concentration when analyzing the passive sampler. Tubes are provided to make it easier, and less wasteful, when determining DE.
