University researchers have developed methods of sensing and identifying vapor analytes based on temperature cycling of an optically interrogated porous optical film sensor. For example, the hysteresis in the temporal response of the photonic stop band from an oxidized porous silica chemical sensor .....

Electroactive analytes can be transported to an EC detector placed relatively far away from the end of a CE separation column providing decoupling of the CE electric field from the EC detectorDetector sensitivity is significantly increased while separation efficiency is enhanced. Larger separation c.....
