Abstract

Methods of measuring the residual adsorption capacity of porous carbon gas filters are virtually non-existent. The main objective of our work is to evaluate the performance of gas sensors that can be operated successfully when embedded in the carbon of a gas filter. This paper describes how polymer-coated SAW sensors have been utilized to monitor the progression of dimethyl methylphosphonate through a filter test bed filled with carbon adsorbent. Performance of the sensor and the breakthrough characteristics of the filter test bed are described. We also describe the design of a miniature, wireless, remotely-powered SAW sensor system
