Comments for Sample AE03914 - Analysis $GCMS
Westchester Dept, of Labs & Research User: Vinci, David L Date: 03-21-2002 Time: 15:57:50
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. The reanalyzed sample had a Surrogate Standard recovery of 145%.
