Description:
Two new performance audit materials utilizing different sorbents have neen developed to assess the overall accuracy and precision of the sampling, desorption, and analysis of semivolatile organic compounds by EPA, SW 846 Method 0010 (i.e., the Modified Method 5 sampling train). he first audit material is an XAD-2 cartridge. t is prepared by spiking known quantities of organic compounds onto XAD-2 resin contained in glass cartridges. he test compounds are recovered and analyzed by using Method 0010 laboratory procedures. arlier studies at RTI showed recovery efficiencies to be between 88 and 98 percent. est compounds spiked onto XAD-2 cartridges show little change (+6 percent) in the amount loaded when stored under refrigeration over an 8-month period. he second audit material is a Carbotrap-TM cartridge. t is prepared by spiking known quantities of test compounds onto Carbotrap adsorbent material contained in stainless steel cartridges. he test compounds are thermally desorbed from the cartridges onto an operating Method 0010 unit. he test compounds are then recovered by using Method 0010 laboratory procedures. arlier studies at RTI showed recovery efficiencies to be between 80 and 108 percent. ive of the six test compound spiked onto Carbotrap cartridges showed little change 7 percent) in the amount loaded when stored at room temperatures over a two-month period. itrobenzene does not appear to be stable on Carbotrap audit cartridges. n interlaboratory study to quantitate the accuracy and precision of the audit materials was conducted with five...
