Comments for Sample AD28964 - Analysis $GCMS
Westchester Dept, of Labs & Research User Vinci, David L Date: 12-15-2001 Time: 09:19:27
A GCMS scan, from 35 to 550 amu, does not reveal the presence of unusual compounds, except for the presence of bis(2-Ethylhexyl)phthalate at an estimated level of 0.43 ug/L. It is also present in the Laboratory Blank at 0.41 ug/L. Recoveries for 5 of the 43 compounds in the LCS Standard were above their acceptance ranges. This sample was received with a pH of less than 2.
