Operational parameters are decided only by experience in traditional electronic nose experiment methods

which can’t make sure the experiments’ repetition and the maximum efficiency.So the design of experiment is introduced to experiment of electronic nose.Central composite design is used to ascertain the experimental point quickly

and for the target of the biggest fuzzy corrected synthetic response

key parameters of preconcentration-electronic nose system is optimized.Theory analysis and experimental result show that the optimization method conductes to repetitious experiment of electronic nose

and which can obtain the maximum experimental information for the minimal experimental cost.
