Fused capillary columns are <br /> preferred to packed columns; a packed column may be used as a "first cut" with "dirty" samples or once the hydrocarbons have <br /> been characterized and proper QA/QC is followed. <br /> For drinking water sources, EPA recommends that the 500 series for volatile organic should be used in preference to the 600 <br /> series because the detection limits are lower and the QA/QC is better. Samples exhibiting any level of heavy metal <br /> contamination may require further analysis. PHS-EHD recommends holding those samples until disposal is indicated. <br /> EH 23 046 (Revised 5/20/96) Page 8 <br />
