Fused capillary <br /> columns are preferred to packed columns; a packed column may be used as a"first cut"with"dirty"samples or <br /> once the hydrocarbons have been characterized and proper QA/QC is followed. For drinking water sources, EPA <br /> recommends that the 500 series for volatile organic should be used in preference to the 600 series because the <br /> detection limits are lower and the QA/QC is better. Samples exhibiting any level of heavy metal contamination <br /> may require further analysis. PHS-EHD recommends holding those samples until disposal is indicated. <br /> EH23 046 (Revised 05/09/00) <br /> EH 23 046(revised 1124/02) <br /> 0.jWA,\epsi3O,h23046."d Page 4 WO#121718 <br />
