摘要
The paper introduces a new type instrument for rapid measuring ATP.The system consists of a micromodule ATP sensor and an instrument for measuring weak light transmitted by optic fiber. The micromodule ATP sensor mainly is composed of enzyme membrane, a probe and a bundle of optic fiber. The instrument measuring weak light consists of photomultiplier, high voltage power, pulse amplifier and counter. The instrument was characterized by simple structure,small size, rapid response time (<5 s), high sensitivity (10-12 mol/L), stable performance (measuring the same sample for 50 times, CV< 5% ), long enzyme storage time (>3 months).
