ASSAY APPARATUS FOR COMPONENT IN LIQUID

摘要

PURPOSE:To measure a plurality of components in a liquid, by arranging a plurality of working poles in an assay apparatus having opposed poles and the working poles. CONSTITUTION:A plurality of electrodes 5-7 are formed on one sensor substrate 4 and one end thereof are formed as connector sections 5a-7a while several different physiologically active substances are immobilized at the other ends 5b-7b thereof to make working poles 1-3. An opposed pole 9 and a connector section 8a are formed on the back of the sensor substrate. A sensor section thus arranged is housed into a cover 10 and then, immersed into a sample liquid accumulated in a reaction tank to detect an object to be measured therein. When physiologically active substances of the same type are immobilized on said working poles 1-3, a stable measurement can be performed as compared with the operation using one working pole.
