Sterile poly tubing is fitted to the <br /> exhaust port and the tedlar bag. Then the sample valve of the <br /> tedlar bag is opened and the bag is filled with the sample Once <br /> the tedlar bag is full, the valve is closed and locked, the sample <br /> port closed, and the appropriate label is placed on the bag <br /> The labels for both the influent and effluent tedlar bag samples <br /> show the dare, tire, Sam-l e Tn* and analyses to be run. <br /> Both the influent and effluent tedlar bag samples are then placed <br /> within a cooler, on ice, and are hand delivered to WEGE' s laboratory <br /> that same day. <br /> r'Vi Amo Tnn; zing <br /> The vapor sample is then injected inuo an <br /> L � ....4 <br /> Detector) chromatograph and the resulting chromatogram compared to <br /> standard chromatograms of known TFH {Total Fuel Hydrocarbons, <br /> gasoline) and BTEX (ben <br /> duelzene' chromatographthd comparison isalso oran <br /> concentrations .
