GCMS Scan For Unknowns
Other unknown compounds ug/L 11/14/2001 DLV
A scan of the extract prepared for the 508 analysis, from 35-550 amu using a mass spectrometer, does not reveal
the presence of non-target compounds, except for 1,2-Dichlorobenzene-d4 at 0.26 ug/L, probably due to laboratory
contamination, since it is used as a Surrogate Standard in GCMS analyses.
