Abstract
Responses of a Micro-hotplate based integrated gas sensor array to CO and CH4were measured with an automated gas sensor calibration system. Combining with the blind source separation (BSS) techniques, the blind separability in gas mixture analysis was discussed. The widely used BSS approach-Independent Component Analysis (ICA) was adopted to verify the proposed method by analyzing the gas mixtures of CO and CH4. The analysis results demonstrate that BSS was an effective way to extract the information of gas components in mixtures, from which the gas concentrations can be estimated. The average relative quantification errors were 9.37% and 8.11% for CO and CH4, respectively, in the specified concentration ranges.
