A new system for rapid measurement of ATP

Abstract

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).
