INTRACELLULAR CALCIUM CONCENTRATION MEASURING APPARATUS

摘要

PROBLEM TO BE SOLVED: To meet the strong customer requirement that a device perform self- diagnosis on its important functions prior to measurement, for taking measurements under highly reliable conditions. SOLUTION: A device of high reliability is provided which can automatically confirm its signal processing functions with a wide dynamic range by having a plurality of reference voltages, and which can monitor deterioration of an optical system and fluctuation of an optical path based upon quantitative measurements by measuring a standard stable emission reagent.
