Analysis Conditions PYMS Sample was analyzed using a Agilent 6890 gas chromatograph in conjunction with a 5975B mass selective detector using a Frontier Laboratories double shot Pyrolyzer model PY3030D. Data acquisition was accomplished using MassHunter software. Sample peaks were compared with over 796,613 reference compounds using the NIST/EPA/NIH mass spectral search program. The following run conditions were applied for gas chromatographic analysis: Sample Size: ~0.7 mg Initial Delay: 2.0 minutes Initial Temperature: 50 ºC Final Temperature: 350 ºC Temperature Ramp Rate 1: 20 ºC per minute Hold Time: 15 minutes Pyrolysis Temperature: 1st pass =100-400 ºC, 2nd pass = 700 ºC Detector Temperature: 315 ºC Injector Split: 80:1 Mass Range: Low Mass = 30 High Mass = 700 Column: Ultra Alloy –PBDE Table 1.
