A rapid and simple procedure has been developed for the simultaneous determination of hydrazine, methylhydrazine, and 1,1-dimethylhydrazine in air at the parts per billion (ppb) concentration level. This procedure utilizes a chilled acetone collection medium which quantitatively traps the hydrazines and converts them to stable derivatives in a single step. The acetone solution is then assayed directly for the derivatives by using a gas chromatography with a nitrogen specific detector. The results obtained from this procedure are in excellent agreement with results obtained by independent analytical techniques, and the overall precision of the methodology is better than 5% (relative standard deviation) for 90 ppb hydrazine. The minimum detectable concentration is estimated to be approximately 4 ppb.
