Comments for Sample AD24401 - Analysis $GCMS

A scan of the extract prepared for the 508 analysis, from 35 - 550 amu using a mass spectrometer, does reveal the presence of a hydrocarbon mixture, probably from an oil related substance. This substance could be in the sample or could have been from a contaminated sample bottle. No other sample so far has been observed to contain a similar substance. No other analysis performed has revealed a similar substance, thus there is no indication of laboratory contamination at this time. The Field Blank for this sample shows no contamination and no unusual organic compounds.
