Fused capillary columns=preferred to packed columns;a <br /> packed column may he used as a"fiNt cut"with"dirty"samples or once the hydrocarbons have been characterized and proper QA1QC is followed, For <br /> drinking water Sources,EPA rmommetrds that the 500 series for volatile ar8anic should be used in preference W the 600 series because the detection limits <br /> arc lower and the QA/QC is bcttct.
