Fused capillary <br />columns are preferred to packed columns; packed column may be used as a "first cut" with "dirty" samples or <br />once the hydrocarbons have been chara erized and proper QA/QC is followed. For drinking water sources, EPA <br />recommends that the 500 series for v the organic should be used in preference to the 600 series because the <br />detection limits are lower and the /QC is better. Samples exhibiting any level of heavy metal contamination <br />may require further analysis. PHS- HD recommends holding those samples until disposal is indicated. <br />EH23 046 (Revised <br />EH 23 046 (revised 1/24/02) <br />c\sale\flp\repairs3-eh23046.wpd Page 4 WO #124679 <br />
