摘要
PROBLEM TO BE SOLVED: To provide a recovery rate evaluation method of polycyclic aromatic hydrocarbons which accurately determine a recovery rate of PAHs by a GC/MS method with a heat desorption device.;SOLUTION: The method includes storing a quartz filter or a silica wool bearing DEP in a heat desorption tube 12, analyzing the heat desorption tube 12 until no PAH is detected by a GC/MS 10 with a heat desorption device; injecting a certain amount of PAHs reference substance, about which concentration of each PAH is known, into a quartz filter 15B where only carbon remains within a heat desorption tube 12a; analyzing the reference PAHs by the GC/MS 10 with a heat desorption device under this condition; and comparing the analysis values with reference concentrations of PAHs of the PAHs reference substance, thereby the recovery rate of each PAH to be analyzed is determined.;COPYRIGHT: (C)2011,JPO&INPIT
