Product Description

AQUA-600M Atomic Fluorescence Heavy Metal Water Quality Online Analyzer

The AQUA-600M Atomic Fluorescence Heavy Metal Water Quality Online Analyzer is a new type of fully automatic online analyzer for measuring heavy metals in water. It is developed based on injection pump platform and combined with atomic fluorescence technology. It can analyzer heavy metal: Hg, Se, As, Cd, Sb, Pb, etc. It is high precision, low detection limit, high stability, and low maintenance for heavy metal online monitoring.  

The analyzer generates an excess of hydrogen gas, heavy metal gases and argon gas through a chemical reaction. The mixture of these gases enters the atomizer. Under the ignition device, hydrogen gas and argon gas form a flame. The heavy metal elements to be measured are in an atomized state. When the gaseous free atoms absorb radiation of characteristic wavelengths, the outer electrons of the atoms transition from the ground state or a lower energy state to a higher energy state. After approximately 10 ^-8 seconds, the electrons transition back to the ground state or a lower energy state, simultaneously emitting fluorescence.

The intensity of the emitted fluorescence is directly proportional to the concentration of the heavy metal. By comparison, the concentration of the corresponding heavy metal element in the sample can be determined.

Application

•    Industrial wastewater

•    Centralized drinking water

•    Surface water

Features

•     Injection pump sampling technology with high measurement precision, minimal cross-contamination between reagents, and automated continuous measurement;

 

•    Shielded quartz furnace low-temperature atomizer reduces fluorescence quenching and gas phase interference, improving atomization efficiency;

 

•    Uses an efficient gas-liquid separation hydride generator and after-discharge technology for efficient gas-liquid separation;

 

•    High-precision flow control monitoring system and high-sensitivity fluorescence photometer enable low-concentration detection of multiple heavy metals;

 

•    Real-time measurement display, calibration, and multi-point linear combination ensure precise and stable instrument measurement;

 

•    Multiple external interfaces, including RS485,RS232,RJ45,USB,etc.
