METHOD AND APPARATUS FOR MEASURING THE CONCENTRATION OF ABSORBING SUBSTANCES

METHOD AND APPARATUS FOR MEASURING THE CONCENTRATION OF ABSORBING SUBSTANCES

A non-invasive system for measuring the concentration of an analyte in an absorbing matrix is described. The system di- rects a beam of radiation at the matrix. The beam consists of a series of successive alternate pulses of electro-magnetic radiation, one of which is highly absorbed by the analyte...

description A non-invasive system for measuring the concentration of an analyte in an absorbing matrix is described. The system di- rects a beam of radiation at the matrix. The beam consists of a series of successive alternate pulses of electro-magnetic radiation, one of which is highly absorbed by the analyte and the other of which is non - absorbed. The transmitted or reflected beam is opti- cally detected and an electrical signal proportional to beam intensity is us ed to adjust the beam intensity and as a measure of ana- lyte concentration.
