Laboratory Phosphate Analyzer

I. Product Overview

The laboratory phosphate analyser is a rapid analysis instrument integrating automatic sampling and photoelectric detection. The instrument performs colorimetric quantification of the reacted coloured solution and obtains the corresponding phosphate content from the built-in standard curve. It is suitable for power plants, chemical and fertiliser plants, metallurgy, environmental protection, pharmaceuticals, chemical fibre and semiconductor industries and for the determination of soluble phosphate ions in demineralised water, steam condensate and boiler water. It is designed and manufactured with reference to 《GB/T 6913-2023 Analysis of water used in boiler and cooling system — Determination of phosphate》.

II. Measuring Principle

The instrument determines the phosphate content of water samples by the ammonium molybdate spectrophotometric method specified in GB/T 6913-2023. In an acidic medium and in the presence of antimony salts, the orthophosphate ions in the sample react with ammonium molybdate to form yellow phosphomolybdic heteropoly acid (phosphomolybdenum yellow). This complex is reduced by ascorbic acid to a stable blue phosphomolybdic heteropoly acid (phosphomolybdenum blue), which has its maximum absorption at 710 nm and whose absorbance is proportional to the phosphate content of the sample. The high-precision photoelectric detection system measures this absorbance and the concentration, expressed as phosphate (PO₄³⁻), is calculated automatically from the built-in calibration curve.

III. Applications

Suitable for power plants, chemical and fertiliser plants, metallurgy, environmental protection, pharmaceuticals, chemical fibre and semiconductor industries; for the determination of soluble phosphate ions in demineralised water, steam condensate and boiler water.

IV. Key Features

1. 7-inch colour touch screen with Android 7.1.1 smart operating system for a better interactive experience and smoother operation.

2. Peristaltic pump continuous automatic sampling: flow-through measurement is not limited by the number of samples, allows continuous multi-sample testing and saves reagents and consumables.

3. Wi-Fi connectivity for fast wireless upload of measurement data.

4. Custom-wavelength, highly stable LED cold light source for more stable data, low power consumption and long life.

5. Preset standard curves and user-defined curves in one instrument, supporting both standardised rapid testing and individual method development for an efficient, flexible workflow.

6. Professional dust cover protecting the peristaltic pump and tubing.

7. Intelligent constant-current voltage regulation with automatic light intensity adjustment and calibration; no light source drift during long continuous operation.

8. Built-in high-speed thermal printer that automatically prints the test report when measurement is complete.

9. 16 GB storage capacity with room for 5 million measurement results.

10. Data cloud platform for long-term storage of results, short- and long-term review and analysis, and assisted management.

11. Direct data copying to a USB drive through a standard driver-free USB port.

12. Self-cleaning function: the tubing is automatically rinsed after measurement.

13. Optional built-in lithium battery power supply.
