Comments for Sample AD28596 - Analysis $GCMS Westchester Dept. of Labs & Research User: Vinci, David L Date: 12-18-2001 Time: 16:11:08
The GCMS scan, from 35 to 550 amu, does not reveal the presence of unusual compounds, except for bis(2-Ethylhexyl)phthalate at an estimated level of 0.36 ug/L. The recovery for the Surrogate Standard in this sample was 71%. Recoveries for 16 of the 44 compounds in the LCS Standard were outside of their acceptance ranges. This sample was re-extracted on 12/3/01 and re-analyzed. Results were similar. The Surrogate Standard recovery was 89% and 1 of the 43 compounds in the LCS Standard was above its acceptance range.
