Abstract

A micro vapor source has been developed for calibrating micro gas chromatograph (μGC) systems. By utilizing a porous silicon wick in a micro diffusion system, vapor generation with excellent stability has been achieved. The source has shown uniform and repeatable vapor generation for n-decane with less than a 0.1% variation in 9 hours, and less than a 0.5% variation in rate over 7 days. The evolution rate follows the diffusion model as expected, although the room temperature rate is higher than theoretically predicted. Equipped with a refillable reservoir, this vapor source is suitable for extended μGC field deployment. (© 2007 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim)
