Analytical module for in-line IR spectroscopy o f chemical reactions in microchannels

摘要

In-line spectroscopy in microchannels can be accomplished using a specially developed analytical module. By means of the micro electrical discharge machining technique (#mu# EDM technique), the respective channel forms are fist cut into metal substrates and then covered by transparent disks on both sides. IR spectroscopic irradiation of the partially transparent microchannels takes place in an IR microscope and yields any number of data along and across a reaction channel depdending on the focus of the measurement IR beam.
