Comments for Sample AE02561 - Analysis $GCMS Westchester Dept. of Labs & Research User: Vinci, David L Date: 03-25-2002 Time: 15:04:33
The GCMS scan, from 35 to 550 amu, does not reveal the presence of unusual compounds. The recoveries for 9 of the 43 compounds in the LCS Standard were below their acceptance ranges. Because of the low Surrogate Standard recovery this sample will be reextracted and reanalyzed. The reextracted sample had a Surrogate Standard recovery of 173%.
