NYC 9/11 Public Portal Document * Comments for Sample AD28692 - Analysis $GCMS
Westchester Dept, of Labs & Research User: Vinci, David L Date: 12-07-2001 Time: 17:03:16
The GCMS scan, from 35 to 550 amu, does not reveal the presence of unusual compounds, except for Di-n-butylphthalate at an estimated level of 0.28 ug/L and bis(2-Ethylhexyl)phthalate at an estimated level of 0.38 ug/L. The recovery for the Surrogate Standard in this sample was 105%. Recoveries for 9 of the 44 compounds in the LCS Standard were outside of their acceptance ranges. The chromatogram reveals contamination which has been identified to be from the TurboVap concentrator.
