AN IMPROVED TOXIC VAPOR DETECTOR FOR HYDRAZINE MONOMETHYLHYDRAZINE AND HC1

AN ALL SOLID-STATE MICRO-ELECTROCATALYTIC AMPEROMETRIC SENSOR IS PROPOSED FOR THE DETECTION, IDENTIFICATION, AND QUANTIFICATION OF HYDRAZINE, MONOMETHYLHYDRAZINS AND HC1. DURING PHASE I, SEVERAL INNOVATIVE SENSORS ARE CONSTRUCTED AND EVALUATED. THE SENSORS USE SOLID IONIC CONDUCTORS AS THE ELECTROLYTE. IMPROVEMENTS IN SENSOR RELIABILITY ARE ACHIEVED BY USING THESOLID-STATE APPROACH. IMPROVEMENTS IN SENSITIVITY ARE ACHIEVED BY USING ELECTRONIC SIGNAL CONDITIONING. AND, IMPROVEMENTS IN SELECTIVITY ARE ACHIEVED USING A SENSOR ARRAY AND COMPUTER ALGORITHM (ARTIFICIAL INTELLIGENCE) TO PRODUCE AND INTERPRET CHEMICAL SENSOR SIGNALS. THE SENSOR DEVELOPMENT IS THE FOUNDATION FOR THE DEVELOPMENTOF FIXED-SITE AND PORTABLE MONITORING INSTRUMENTATION FOR THE TARGET TOXIC VAPORS.
