Preliminary Operating Conditions

The Hewlett Packard 5890A Series II

Gas Chromatograph or the Shimadzu Gas Chromatograph 14-A (GC), each equipped with a photo-ionization detector (PID) and an electron capture detector (ECD) in series, will be utilized to analyze the samples. The GC column temperature will run isothermally for 3 minutes at 50°C, then temperature ramp at 10°C/min to 170°C, while the injector temperature is at 180°C and the detectors are at 225°C.

It should be noted that the instrument operating conditions noted above are preliminary. The conditions will be modified in the field, as necessary, to optimize instrument performance.
