Westchester Dept, of Labs & Research User Vinci, David L Date: 12-17-2001 Time: 12:41:53
The GCMS scan, from 35 to 550 amu, does not reveal the presence of unusual compounds, except for the presence of di-n-butylphthalate at an estimated level of 0.31 ug/L. It is also present in the Laboratory Blank at 2.72 ug/L. Recovery for 1 of the 43 compounds in the LCS Standard was above its acceptance range.
