Comments for Sample AD29233 - Analysis $GCMS Westchester Dept, of Labs & Research User: Vinci, David L Date: 12-18-2001 Time: 16:05:42
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 0.32 ug/L. Also present is Nonadecanol at an estimated level of 0.93 ug/L and a fit of 93 out of 100. its presence is probably due to laboratory contamination. The Field Blank, AD29228, associated with this sample was clean. The recovery for 1 of the 43 compounds in the LCS Standard was above its acceptance range.
