Key Design Features

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.

Selector Valve Assembly
- Enables flexible reagent sampling timing and diverse channel configurations.
- Minimizes dead volume for easy maintenance and extended service life.
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 at 0.7 mL per dose, significantly reducing reagent usage.
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.
Sealed Digestion Unit
- Operates under high-temperature and high-pressure conditions to accelerate reactions.
- Eliminates corrosion risks from volatile gases in open systems.
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

Following acid digestion, the water sample is combined with a pH-adjusting reagent and subsequently oxidized with potassium persulfate. Under alkaline conditions (pH 10.5 ± 0.2) in the presence of dithizone as the chromogenic agent, lead(II) ions form a cherry-red dithizonate chelate complex (λ_max = 520 nm). A microprocessor-controlled spectrophotometer quantifies lead concentration through differential absorbance measurement calibrated against NIST-traceable standards, with the chelate complex concentration demonstrating a linear correlation (R² ≥ 0.995) to total lead content.
