1、 Purpose and Scope of Application
Grain heavy metal rapid detection boxIt is a specialized equipment for rapid detection of lead and cadmium heavy metals in grain. It adopts dilute acid extraction technology, immunomagnetic bead technology, electrochemical technology, and combines portable integrated design to integrate pre-treatment and terminal detection, achieving rapid, high-throughput, and high-precision analysis and testing of lead and cadmium in grain samples such as rice, wheat, corn, and soybeans. Used for grain and oil quality inspection units, rice storage enterprises, rice mills, breeding units, research institutes, etc.
2、 Product Features
1. Efficient and fast: dual channel testing position, simultaneous detection of cadmium and lead content, batch detection ≤ 14 minutes/sample.
2. Stable performance: High sensitivity, detection limit up to 0.02ppm, multi parameter calibration, stable performance, accurate and reliable results.
3. Easy to operate: Equipped with a dedicated reagent kit, the operation is simple and easy to learn, with low requirements for testing personnel.
4. Integrated and portable: With an integrated box design and built-in pre-processing and mixing equipment, it is compact and portable, suitable for procurement sites.
5. Detection mode: Dual mode of fast screening and precise detection, equipped with different reagent kits to meet different detection needs.
6. Easy to maintain: Adopting disposable screen printed electrodes, no need for polishing and maintenance.
7. Safety and Environmental Protection: The instrument has a built-in standard curve, eliminating the need for standard products, ensuring safety and environmental protection.
