In support of investigation or remediation activities at underground fuel tank sites, AirTECHNOLOGY provides the expertise to meet the strictest requirements, and the capacity to handle large or small sample loads for the analysis of benzene, toluene, ethylbenzene, xylenes, methyl-tert-butylether, hexane and total volatile petroleum hydrocarbons. Samples are usually collected in Tedlar bags by pumping soil vapors or ambient air into the bag. Due to the relatively short holding time associated with Tedlar bags (three days), the samples are rushed to the laboratory for analysis. Upon receipt, the samples are inspected for any damage or leakage that might compromise the data quality. The samples are analyzed by a gas chromatograph equipped with FID and photoionization detectors (PID). A sample loop is filled with a portion of the sample and then swept into the GC for analysis. Quality control consists of analysis of a laboratory control sample, laboratory duplicate control sample, method blanks, and verifiable calibration standards. The Table above lists the routine analytes reported for this method. | |||||||||||||||||||
