Description
Summary:The construction of an amino functional polymer-coated piezoelectric crystal-based sensor for the detection of gaseous sulfur dioxide in gas mixtures at ambient concentrations is described, and results are presented from a study of the effects of various factors in terms of sensor response. The detection system and the coating procedure are detailed. The results from the validation experiments show that polyethylene glycol was a suitable coating material for detecting SO sub(2) at ambient levels, and (2-hydroxypropyl) ethylenediamine was suitable for measuring higher concentrations of SO sub(2).
