摘要

In this paper are addressed two important, but seemingly unrelated issues: long term performance of a gas sensing array and performance of an air purification unit. It is shown that when considered together, the system can be regarded as a “smart filter”. The enhancement is achieved by periodic differential sampling and measurement of the “upstream” and “downstream” gases of a filter. The correctly functioning filter supplies the “zero gas” from the downstream for the continuous sensor baseline correction. A key element in this scheme is the synthetic jet that delivers well-defined pulses of the two gases. The deterioration of the performance of the “smart filter” can be diagnosed from the response pattern of the sensor. The approach has been demonstrated on removal/sensing of ammonia gas from air.
