A new quality and quantity analyzing method for waste gas from chemical industry, especially for acrylic acid ester using air-sampling combined with GC/MS and honeywell air purifier system was firstly advanced in this paper. According to the experiments, the maximum disposal capability of the honeywell air purifier system for acrylic acid ester gas was calculated as about 1 kg x h(-1) and the feasibility and validity of the method was also proved by parallel tests.
