METHOD FOR EXECUTING TIME-DETERMINED ANALYSIS IN PHYSICAL OR CHEMICAL EXAMINATION OF SUBSTANCES AND AN APPARATUS FOR EXECUTING THE METHOD

摘要

The invention concerns a method for measuring the magnitudes of a great number of quantities which may vary very rapidly within wide limits. Each of the magnitudes to be measured is converted into a light signal having an intensity corresponding to the magnitude of the respective quantity. All such light signals are individually integrated during successive, accurately defined time intervals. At the end of each interval it is determined which integrals having reached at least one of a plurality of predetermined levels.
