• Description:
  Although existing sampling and analytical methods for ammonia may be adequate for evaluating exposure relative to the OSHA-PEL (50 ppm TWA), many projects involving the short-term measurement of ppb concentrations require more sensitive methods. This project focuses on the modification of a fluorometric method previously developed for analysis of ammonium in marine and freshwater samples to enable measurement of low concentrations of ammonia in ambient air. The modified approach combines the sorbent-tube collection techniques of current methods for ammonia sampling with analysis using a digital filter fluorometer. [Description provided by NIOSH]
