Comments for Sample AE04027 - Analysis $GCMS Westchester Dept, of Labs & Research User: Vinci, David L Date: 03-21-2002 Time: 16:02:02
The GCMS scan, from 35 to 550 amu, does not reveal the presence of unusual compounds. The recoveries for 2 of the 43 compounds in the LCS Standard were above their acceptance ranges. This sample will be reextracted and reanalyzed due to the low Surrogate Standard recovery. This sample is the Field Blank. The reanalyzed sample had a Surrogate Standard recovery of 134%.
