Product Introduction

The Radioactive Water Sample Evaporation and Acid Digestion Concentrator (also known as: Total α/β Radioactivity Water Evaporation Concentrator) integrates far-infrared radiation heating systems, intelligent sampling systems, and high-precision concentration quantification systems in accordance with national standard methods. It features adjustable heating power, constant temperature heating, modular heating source conversion, stepwise slow sample feeding, evaporation concentration quantitative control, intelligent voice alarms, and automatic sealing upon completion of concentration. This enables unattended, intelligent, automatic, safe, and reliable evaporation and concentration of various samples.
Application Scope

The Radioactive Water Sample Evaporation and Acid Digestion Concentrator is suitable for the water quality and tap water industry, providing fully automated pretreatment for evaporation, concentration, and acid digestion of water samples during the detection of total α, β, and other radioactive water samples. It is also used for automatic evaporation and concentration of environmental air dustfall samples, evaporation and concentration for total dissolved solids (TDS) projects, and other large-volume water sample concentration processes.

Technical Advantages

1. PLC control system, 7-inch large touch screen, one-click start, constant temperature heating, stepwise sample feeding, automatic flow path switching, and automatic concentration quantification;
2. Direct quantification using porcelain evaporation dishes, following national standard methods without the need for sample transfer;

3. Utilizes far-infrared radiation heating devices for uniform heating, programmable PID constant temperature control, and individual control per heating well;
4. High-precision peristaltic pump combined with a quantitative module automatically adds samples during the experiment and continues the process by adding quantitative samples after concentration is achieved;

5. Sensor-based quantitative detection system with ±1g accuracy, allowing independent setting of total addition volume, single addition volume, and final concentration volume; automatically stops the experiment when the set volume is reached;
6. Built-in positive pressure air purge inside the main unit to prevent acid mist from entering and causing corrosion;

7. After the experiment, the sample feeding pipelines can be cleaned automatically by吸入純水 (sucking in pure water) for comprehensive cleaning;

8. The Radioactive Water Sample Evaporation and Acid Digestion Concentrator can be upgraded for automatic acid addition, enabling fully unattended operation and improving experimental efficiency.
