摘要

This paper reports a quantitative electronic nose (enose) for the quantitative determination of Freon gas within the concentration range 0-1000 ppm in the presence of interfering gases such as water,lubricant and petrol vapours.This quantitative neose is a new type of Freon detection system,composed of an array of four sensors.The predicted results are satisfied with a pass rate of >80% within the permited relative errors.The results show that the Freon enose developed in this study is reliable for both the qualitative and quantitative determination of Greon gas and exhibits the merits of high sensitivity,anti-interference and accuracy.
