A scan of the extract prepared for the 508 analysis, from 35-550 amu using a mass spectrometer, does not reveal the presence of non-target compounds, except for 1-Hexadecanol at an estimated level of 1.1 ug/L, and with a fit of 46 out of 100; and 3,7,11-tri- 2,6,10-Dodecatrien-1-ol at an estimated level of 1.5 ug/L, and with a fit of 56 out of 100. A reanalysis of this sample on 12/26/01 reveals it to be clean.
