Key Features

Unique Design: This product features a distinctive design that ensures lower failure rates, reduced maintenance requirements, minimal reagent consumption, and higher cost-effectiveness compared to similar products.

1. Selector Valve Assembly

Enables flexible reagent sampling timing and diverse channel configurations.
Minimizes dead volume for easy maintenance and extended service life.

2. Micro-Dosing Unit

Utilizes a visual photoelectric system for precise reagent measurement, eliminating quantitative errors caused by peristaltic pump tube wear.
Achieves accurate micro-dosing with 0.7 mL per dose, significantly reducing reagent usage.

3. Sample Introduction Unit

Employs a peristaltic pump with negative pressure suction, creating an air buffer zone between reagents and the pump tube to prevent corrosion.
Simplifies and enhances flexibility in reagent mixing.

4. Sealed Digestion Unit

Operates under high-temperature and high-pressure conditions to accelerate reactions.
Eliminates corrosion risks from volatile gases in open systems.

5. Reagent Tubing

Uses imported modified PTFE (polytetrafluoroethylene) transparent tubing with an inner diameter >1.5 mm to minimize clogging by particulate matter in water samples.

Analytical Principle

In the presence of potassium persulfate, nitrogen-containing compounds in the water sample are completely converted to nitrate nitrogen after high-temperature digestion. Under acidic conditions, the nitrate nitrogen reacts with an indicator reagent to form a colored complex. The analyzer detects this color change, converts it into a total nitrogen concentration value, and outputs the result. The amount of colored complex generated corresponds to the total nitrogen concentration.
