Comments for Sample AD25874 - Analysis $GCMS
Westchester Dept, of Labs & Research User: Vinci, David L Date: 01-18-2002 Time: 17:51:15
A scan of the extract prepared for the 508 analysis, from 35 to 550 amu using a mass spectrometer, does not reveal the presence of non-target compounds, except for 1,1,2,2-Tetrachloroethane at an estimated level of 0.48 ug/L and a fit of 95 out of 100. Analysis of the Field Blank for this sample shows no contamination.
