The new national standard (GB/T 45131-2025) leads the innovation of water quality analysis in the power industry: AOSCITECH iChem D1 empowers the industry with cutting-edge technology to upgrade compliance
On August 1, 2025, the State Administration for Market Regulation and the National Standardization Administration jointly issued GB/T 45131-2025 "Analysis Methods for Boiler Water and Cooling Water - Spectrometric Method Based on Intermittent Analysis System", which was officially implemented. This standard, which fills the domestic gap, systematically regulates the intermittent analysis methods of seven key water quality indicators, including phosphate, chloride, and silicate, for the first time, providing a unified technical standard for the safe operation of thermal systems in the energy and power industry. In this standardization revolution, AOSCITECH has become the core force driving industry compliance upgrades with its iChem D1 series of fully automatic intermittent chemical analyzers.
The new standard reshapes industry rules through three core innovations:
Full coverage of indicators: For the first time, seven parameters including phosphate, total alkalinity, and iron have been included in the mandatory testing scope, solving the pain points of scattered standards and missing indicators previously;
Precision quantification control: Clarify the measurement accuracy range and tolerance requirements of various parameter spectrophotometry methods, such as controlling the detection error of silicates within ± 2% to ensure cross laboratory comparability of data;
Standardization of processes: Unified reagent formulas, parameter settings, and operating procedures. If chloride detection is specified, mercury thiocyanate spectrophotometry should be used to reduce human operational errors.
Standardization of processes: Unified reagent formulas, parameter settings, and operating procedures. If chloride detection is specified, mercury thiocyanate spectrophotometry should be used to reduce human operational errors.

AOSCITECH iChem D1: A versatile solution that perfectly matches and surpasses the new national standard
As a benchmark enterprise in the global automation analysis field, AOSCITECH's iChem D1 series not only fully complies with the new national standard, but also redefines water quality testing with four major advantages:
1. Full dimensional compliance, surpassing national standard boundaries
The analysis method of iChem D1 series is highly compatible with GB/T 45131-2025, while expanding the detection items and hardware configuration:
2. Minimalist operation, ushering in the era of unmanned operation
One click operation: from startup preheating to data export, the entire process is automated, and laboratory personnel only need to place samples;
3. Intelligent calibration: Built in AI algorithm for fully automatic inspection, eliminating errors caused by human intervention;
Remote monitoring: supports cloud data transmission and abnormal warning, and management personnel can grasp the device status in real time.
4. Green and efficient, reshaping cost models
By upgrading core technology, only microliters of reagent consumption are required, achieving a win-win situation for environmental protection and efficiency for the enterprise.
Global verification: 100000 sets of data create a reliable foundation for detection
AOSCITECH fully automatic chemical analyzer has undergone large-scale technical validation in laboratories of universities in Germany, Canada, South Korea, Australia, China and other countries. With 100000 sets of sample test data and technical validation by more than ten university laboratory teams, the results are accurate and reliable, perfectly matching various application scenarios.
With the implementation of the GB/T 45131-2025 standard, the energy and power industry is accelerating towards the era of precision and intelligence. The AOSCITECH iChem D1 series, with its triple advantages of "standard compatibility, technology transcendence, and deep cultivation of scenarios", not only provides users with compliant and worry free testing tools, but also helps the industry achieve carbon reduction goals through designs that reduce reagent consumption and waste liquid emissions.
Driven by the dual strategy of "dual carbon" and the development of new quality productivity, AOSCITECH is writing a new chapter in the field of water quality analysis with innovation - making every drop of water carry precision and every test trustworthy.
