• Description:
  NIOSH Method S91 for the determination of 1,3-butadiene (106990) in air was reevaluated, and a new method was developed. Method S91 was reevaluated with respect to recovery, breakthrough volume, and potential chromatographic interferences. Limitations to Method S91 included the fact that the lower quantitation limit appeared to be about 3.4 parts per million (ppm) and the packed column gas chromatographic analysis was subject to interference. The new method developed, Method 1024, employed collection on tandem coconut shell charcoal tubes, desorption with methylene-chloride, and high resolution gas chromatographic analysis. Evaluation of Method 1024 indicated that it should be useful for determining full shift time weighted average exposures in humid air at concentrations ranging from 0.4 to 10ppm. The sampler's capacity should permit quantitation of levels up to 100ppm if desorbed samples are diluted so that they fall in the calibration range. In the chromatographic process, the combination of backflushable precolumn and aluminum- oxide fused silica capillary analytical columns offered the advantages of enhanced sensitivity, enabling detection down to for confirmatory techniques.
