Abstract
J A simple, rapid colorimetric procedure is described for measuring microgram quantities of 1,1-dimethylhydrazine (UDMH) in blood and water. The method, with minor modification, has also been adapted for analysis of air samples. The report provides a calibrated range for analysis of 1-60 micrograms UDMH per milliliter fluid and of 2.5-50 ppm in air; its useful range may be considerably extended by manipulative dilution techniques. The test has additional, limited qualitative application to the analysis of urine.
