GCMS Scan For Unknowns
Other unknown compounds ug/L 3/20/2002 DLV
The GCMS scan, from 35 to 550 amu, does not reveal the presence of unusual compounds. Recoveries for 9 of 43
compounds in the LCS Standard were above their acceptance ranges, while one was below. This sample was
extracted and analyzed twice because the LCS Standard was low the first time. Surrogate Standard recoveries
where acceptable both times.
