NON-SEGMENT CONTINUOUS FLUID ANALYSIS METHOD ON BASIS OF INTERACTION OF FIXING MATERIAL POSITIONED IN FLOW CELL AND RADIATION

摘要

One or more components are determined in a sample by bringing said sample, which can be a liquid or a gas, into contact with a medium for adsorbing or taking up the components in question. A light beam (4) is led via an optical cable through the medium (3) containing the adsorbed or taken-up compound sought for, is reflected against a reflector material (5) back through the medium (3), and the emitted light beam (6) is detected. In enzymatic reactions, inter alia, a membrane (7) can be utilized between sample solution and reagent, said membrane enabling the actual component to diffund through the membrane and react with the enzyme, avoiding thereby the measurements to be disturbed by strong coloration and/or a high content of impurities in the sample solution. The membrane thereby serves as a reflector material for the light beam.
