INDICATOR SYSTEM FOR DETERMINING ANALYTE CONCENTRATION

摘要

A method for quantitatively sensing, using an indicator system based on d iffusion in space and time of a reaction front, for determining and reportin g the prevailing concentration or exposure history of an analyte in food, be verage, and pharmaceutical monitoring for the state of quality, for ripeness indication in fruit, for monitoring environments for concentrations of sani tisers, pollutants and nutrients, for monitoring the residual life of filter s, and for monitoring stream flows.
