Comments for Sample AE08934 - Analysis $GCMS
Westchester Dept, of Labs & Research User: Vinci, David L Date: 05-07-2002 Time: 14:14:48
The GCMS scan, from 35 to 550 amu, does not reveal the presence of unusual compounds. This sample was extracted and analyzed twice with Surrogate Standard recoveries of 61% and 44%. A malfunctioning syringe used during sample preparation is the cause of these low recoveries rather than extraction inefficiency.
