Single Sensor Gas Analysis Using a Microfluidic Channel

Article Preview

Abstract:

We have recently disclosed a novel technique for gas analysis based on monitoring the free diffusion-physisorption of the analytes in a microfluidic channel. Equipped with a single general gas sensor, the prototype can recognize variety of gases and gas mixtures. Here, the structural details of the fabricated prototype are given. The performance of the prototype is demonstrated by presenting analysis results obtained for a number of pure and mixed gaseous analytes.
