Comments for Sample AE10205 - Analysis $GCMS Westchester Dept. of Labs & Research User: Vinci, David L Date: 05-21-2002 Time: 12:05:35
The GCMS scan, from 35 to 550 amu, does not reveal the presence of unusual compounds. The recovery for 1 of the 43 compounds In the LCS Standard was low. This sample will be re-extracted because of the low Surrogate Standard recovery. This sample is the Field Blank. Re-analysis yielded a Surrogate Standard recovery of 85%.
