| Abstract: | Three quality control index of eight kinds of aromatic hydrocarbons,including relative bias of duplicates,recovery of blank spike and sample spike,were studied by sample test using purge and trap-gas chromatography-mass spectroscopy,and also by evaluating data collected from many labs national-widely.The quality control index were produced according to every target.The results showed that the maximum relative bias should be within 6.5%~13.2%;the blank recovery should be within 78%~87% when the spiking conce... |
