EPA 540 方法：使用 Agilent Plexa 萃取柱选择有机污染物

EPA Method 540 has been run using the Agilent Plexa SPE cartridge, Agilent Infinity 1290 HPLC System, and the Agilent 6460 Triple Quadrupole LC/MS. Using all 17 compounds that were in the Draft Method 540, recoveries were well within the range specified by the method, with the exception of one compound. Precision easily met the method requirements for all 17 compounds. All LCMRLs were either near or significantly below EPA required levels, and the method run time was less than half that quoted for Method 540. Agilent 1200 系列液相色谱－芯片／质谱系统
