Comments for Sample AE08264 - Analysis $GCMS
Westchester Dept, of Labs & Research User: Vinci, David L Date: 05-06-2002 Time: 12:07:55
The GCMS scan, from 35 to 550 amu, does not reveal the presence of unusual compounds. This sample will be reextracted and reanalyzed because of a low Surrogate Standard recovery of 69.2 %. Re-extraction has a Surrogate Standard recovery or 94%.
