AMPEROMETRIC PROPELLANT-COMPONENT DETECTOR

Abstract

The data obtained in production of an improved multipurpose detector capable of measuring low airborne concentrations of N2O4, O3, N2H4, unsymmetrical dimethylhydrazine (UDMH), and 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/ppm of N2O4, 52 microamperes/ppm of O3, 40 microamperes/ppm of H2N2, and 20 microamperes/ppm of UDMH. The Amperometric Propellant-Component Detector features self-powered and/or line operation, a built-in rectifier system, a split air-flow system to reduce baseline shift, and a charcoal-sample air by-pass to give the best system for zero checking. The instrument has an effective current gain of 35, and has an input resistance of 10 K ohms. The instrument was provided with a range switch of X 100, X 10, and X 1. Resistor values for providing X 20, X 10, X 5, X 2, and X 1 operation were obtained by actual shunt substitution. (Author)
