Abstract Thermo Scientific Gallery Automatic Discrete Analyzer is special for water analyzing, and can automatically run steps includeing sample and reagents dispensing, water blank, mixing and incubation, Colorimetric reading and data processing. This method refers to U.S. Environmental Protection Agency. The instrument has advantage in low sample and reagents consumption, sensitivity and repeatability; test process can be automatic, standardized and informationized, and is applicable to multitudinous sample testing in water qualities and environmental monitoring.
