Abstract:

The feasibility of utilizing gas adsorption phenomena in the identification and quantitative determination of various gaseous materials was investigated. Factors influencing the performance of the various components of an experimental gas analyzer based on the measurement of characteristic adsorption energies are discussed. Instrumentation specifications included ability to detect and measure concentrations of 10 ppm or less of NO, NO2, N2O3, HCl, HF and O3 in air, irrespective of the mixture involved. The system involved passing the air for analysis through a sensing cell which was to measure the heat of adsorption of the contaminant on an adsorbentcoated thermistor. On the basis of experimental and theoretical analysis it was concluded that a gas sensing device based on the principle of differential heats of adsorption is not feasible.
