NIOSH-approved, commercially-available Florisil tubes were found to quantitatively collect PCB from natural gas streams when the sampling rate is less than 600 cc/min and less than 230 liters of gas is collected. It was also found that severe skewing of the Aroclor pattern can result when gas passes through a PCB contaminated pipe. When this occurs the pattern recognition approach used for quantifying PCB in air samples will be inadequate. In this situation confirmation of PCB should be done using a second GC column and, if PCB's are confirmed, the Webb-McCall or perchlorination procedures should be utilized for sample quantitation.
