This method is for the determination of phenylhydrazine. The sample is collected using a glass midget bubbler containing 15mL of 0.1M HCl, followed by visible spectrophotometric analysis. The working range is 1.1 to 11 ppm (5 to 45 mg/m³) for a 100-L air sample. Note: This is Method S160 in a revised format.
