A method for measuring the absorptionsvermoegens of through flow samples and flow cell, in particular for carrying out this method

摘要

ABSTRACT OF THE DISCLOSURENovel photometric apparatus having a conical shaped flow-cellcomprising a light source proximate the narrow end and a photosensitivedetector at the wider end of the cell. The flow-cell adequately compensatesfor or avoids a lens effect that has been discovered to be a substantialfactor in electro-magnetic energy absorption studies on liquid streams.
