i <br /> REPORT TO: Marty Thorpe !I <br /> JOB REFERENCE: 85-052-5343 <br /> SAMPLE ID: 826664 , Waste Oil <br /> :ATE: 10-20-88 <br /> ANALYSIS: PCB's via Method 8270 <br /> i� <br /> PURPOSE: The perpose of the analysis was to identify and quantitate <br /> any PCB ' s present using the Mass spec EFA method 8270. <br /> u <br /> PROCEDURE: The sample was extracted using EPA method 3550 with a <br /> solvent exchange into he�.ane. Due to the e-.tremely oily <br /> matri-. of the sample a sulfuric acid clean-up was performed, <br /> therefore the 8270 surrogates were destroyed. <br /> DISCUSSION: The sulfuric acid clean-up was notl able to clean up all <br /> the interferences present in the full scan mass spec method <br /> (8270 ). Due to the massive amount, of interference, the <br /> sample was also run on an ECD detector to support the 8270 <br /> data. <br /> ESULTS: Both the 8270 and ECO results are reported: <br /> i <br /> �i <br /> Client : THORPE OIL ro,lect No. : 85-052-5343 <br /> o <br /> Sample ID: 826664 , Wast Oil <br /> Det .
