Product Overview
HM-GSG is a laboratory trace silicate analyzer for measuring soluble silicate ions in water samples. It combines automatic peristaltic-pump injection with photoelectric colorimetry. Applications include desalinated water, steam condensate and boiler water in power, chemical and fertilizer, metallurgy, environmental protection, pharmaceutical, chemical fiber and semiconductor applications.
The measurement principle uses soluble silicon reacting with ammonium molybdate at pH 1.1–1.3 to form a yellow silicon-molybdenum complex. Ferrous ammonium sulfate reduces the complex to silicon-molybdenum blue. The analyzer measures absorbance and determines silicon content according to the stated photoelectric colorimetric method and Lambert–Beer relationship. The design references GB/T 12149-2017 for silicon determination in industrial circulating cooling water and boiler water.
Key Features
- 0–200 μg/L measurement range, calculated as SiO₂, for trace-level silicate work.
- Automatic flow injection supports continuous multi-sample testing without manual sample addition.
- Seven-inch color touch screen with an Android smart operating system.
- Preset and user-defined calibration curves support routine measurement and method development.
- Customized-wavelength LED cold light source with automatic light adjustment and calibration.
- Wi-Fi upload, USB export, built-in thermal printing and 16 GB storage for up to 5 million results.
- Automatic pipeline cleaning and a protective cover for the pump and tubing; an optional built-in lithium battery is stated in the product source.
Applications
- Trace soluble silicate testing in desalinated water, steam condensate and boiler water.
- Laboratory and process-support testing in power plants, chemical and fertilizer production, metallurgy, environmental protection, pharmaceuticals, chemical fiber and semiconductor operations.
- Prepare the water sample and carry out color development using the procedure for the selected silicate test.
