Fused capillary columns are preferred to packed columns; a packed column may be used as a "first cute with 'dirty" samples or once the hydrocarbons have been characterized and proper QAIAC is followed. For Drinking water sources, EPA recommends that the 500 series for volatile organics be used in preference to the 600 series because the detection limits are lower and the QAJQC is better. Samples exhibiting any level of heavy metal contamination may require further analysis. PHS-EHD recommends holding these samples until disposal is indicated. EH 23 048 (Revised 7/10,92) Page 3
