Evaluation of Tenax thin films as adsorbent material in a micro-preconcentrator and its operation as a valve-less multiple injection system in micro-gas chromatography


This paper aims to evaluate Tenax TA in the form of thin films as an adsorbent material as an alternative to its solid form counterpart (granular form) for micro-preconcentrators. The micro preconcentrator (μPC) consists of embedded high-aspect-ratio three-dimensional micro-pillars coated with Tenax adsorbent. This μPC has inner dimensions of… (More)
