ATR microreactor: A tool for in-situ and spatial reaction monitoring

Abstract

We report the fabrication of a microreactor with embedded internal reflection element (IRE) and herringbone (HB) micromixer. The microreactor can be used as a powerful tool for monitoring in-situ chemical reactions when combined with attenuated total internal reflection (ATR) infrared (IR) spectroscopy. In this work, a H2O/D2O model reaction was monitored as a proof of concept and the HOD product formation was spatially tracked. In addition to this, a mixing efficiency of 99% at 25 cycles was also calculated for the microreactor.
