Comments for Sample AD29231 - Analysis $GCMS Westchester Dept. of Labs & Research User: Vinci, David L Date: 12-18-2001 Time: 15:42:10
The GCMS scan, from 35 to 550 amu does not reveal the presence of any unusual compounds, except for bis(2-Ethylhexyl)phthalate at an estimated level of 0.42 ug/L. The recovery for 1 of the 43 compounds in the LCS Standard was above its acceptance range. The recovery for the Surrogate Standard in this sample was below 70%. This sample will be re-extracted and re-analyzed.
