Abstract
Method No. S120 for the detection and assay of chlorodiphenyl 42% chlorine (Aroclor-1242) (53469219) was tested and found to be unacceptable. The method failed for two reasons: the number of man hours required exceeded the allotted amount, and an electron capture gas chromatography detector was used and found to be unsatisfactory because the linear range and sensitivity decreased during the course of the study. Because of the decreased sensitivity and contamination of the detector, the results were not reproducible within 10% of the 0.5X OSHA level. Therefore, generated samples, standards, and spiked samples could not be analyzed within an acceptable degree of confidence.
