The data obtained in production of an improved multipurpose detector capable of measuring low airborne concentrations of nitrogen tetroxide (N2O4, ozone (O3), hydrazine (N2H4), unsymmetrical dimethylhydrazine (UDMH), and hydrogen fluoride (HF) is presented. The concept of "forward and reverse polarization" was applied and considerable specificity was obtained for oxidizing and reducing substances. Sensitivities were obtained of 100 microamperes per part per million of nitrogen tetroxide, 52 microamperes per part per million of ozone, 40 microamperes per part per million of hydrazine, and 20 microamperes per part per million of unsymmetrical dimethylhydrazine. || ABSTRACT AUTHORS: Author
