Abstract The U.S. Environmental Protection Agency (EPA) reference method used for collecting hydrogen chloride and chlorine in stack gas emissions is SW-846 Method 0050. In Method 0050 gaseous and particulate pollutants are withdrawn from the stack at a rate proportional to the flow rate of the gas emissions through the stack and are collected in a cyclone, on a filter, and in absorbing solutions. As the method requires, the cyclone is purged at the end of sampling with clean ambient air. These studies showed that this was an effective way to transfer the residual hydrogen chloride from the cyclone to the impingers as long as no more than 25 ml of liquid was collected in the cyclone. At very low concentrations hydrogen chloride appears to be lost in the sampling equipment before being collected in the absorbing solutions and the loss appears to increase as the moisture content of the stack emissions increase. The presence of ammonium chloride introduces a positive error under all conditions tested.
