Analysis of 2-propanol in exhaled breath using in situ enrichment and cataluminescence detection

Luminescence. 2011 Mar-Apr;26(2):125-9. doi: 10.1002/bio.1194.

Abstract

We report a simple gaseous sensor for the sensitive detection of trace 2-propanol in exhaled breath using in situ enrichment and cataluminescence detection method on the surface of nanomaterials. The influences of heating voltage and absorption time on the CTL intensity were discussed, respectively. In the selected conditions, the linear range of 2-propanol concentration is 60-600 ppbv and the detection of limit is 11 ppbv. Moreover, the lifetime and selectivity of the sensor were also investigated. It has the potential to diagnostic volatile organic compounds in human breath.
