A scan of the extract prepared for the 508 analysis, from 35-550 amu using a mass spectrometer, does reveal the possible presence of 4-ethoxy-benzoic acid ethyl ester at an estimated level of 1.1 ug/L and bis(2-Ethylhexyl)decanedioic acid at an estimated level of 42 ug/L. Also present in the chromatogram are compounds from column bleed. The Field Blank for this sample will be analyzed.
