Application of High Precision ADC in Seawater Total Organic Carbon Quick Measurement

Article Preview

Abstract:

Aiming at the requirement of fast-response high-precision in seawater Total Organic Carbon ( TOC) quickly measurement, this paper presented a design scheme based on AD7799.The system took 24-bit △-∑ ADC AD7799 as the core and HAMAMATSU H5784 Photo Multiplier Tube (PMT) as photo-electric sensor. The design realized the measurement of chemiluminescence that correlates to seawater TOC. The experiments in the laboratory and Qingdao sea area show that the system possesses stable operation and high reliability. The experiment results show that the measurement resolution exceeds 0.001 mg/L and the measurement accuracy is 0.01 mg/L.
