Westchester Dept, of Labs & Research User. Vinci, David L Date: 06-05-2002 Time: 15:13:17 2** *e- bis(2-ethylhexyl)phrhalsate in LB and FB is 3 ug/l. 5 of 18 compounds fail in LCS Standard. 2 of 18 compounds fail in Spiked sample. 1 of 3 Surrogates fail in sample. LB and sample contaminated with Turbo vap grease. Analysis will be repeated on fresh bottle. Samples may contain unknows such as hydroxynitrophenyl pyridine at .07 ug/l fit 53, biphenyldiamine at 4.6 ug/l fit 72, and guanosine at 0.09 ug/l fit 37. This sample was reextracted on 5/23 and reanalyzed on 5/29. One of the 3 Surrogate Standards, Perylene d-12, was low. This is due to a reaction between it and the sample preservative, and can not be avoided. Hydrocarbons present in this sample are also present in the LAboratory blank. They are being produced from the Solid Phase Extraction cartridges. A remedy to this situation will have to determined.
