Preoxidation for colorimetric sensor array detection of VOCs. [PDF]

open access: yesJ Am Chem Soc, 2011
A disposable preoxidation technique that dramatically improves the detection and identification of volatile organic compounds (VOCs) by a colorimetric sensor array is reported. Passing a vapor stream through a tube packed with chromic acid on silica immediately before the colorimetric sensor array substantially increases the sensitivity to less ...
