• Description:
  Performance tests for evaluating diffusive samplers have been set up so as to permit the evaluation of a large number of sampler/analytes. Experimentation has been minimized by omitting re-evaluation of the exposure chamber at each sampler evaluation. Furthermore, a single figure of merit, the symmetric-range accuracy, is obtained for each sampler/analyte by combining measured sampler environmental sensitivity with a set of nominal environmental characteristics selected with the expected application in mind. The result is a means of deciding sampler suitability by selecting a value for acceptable accuracy. Also, confidence intervals containing measurand concentrations at probability > 95% may be obtained at given confidence (e.g., 95%) in the performance evaluation. A pilot test of the performance protocol is described. [Description provided by NIOSH]
