The automatic lead cadmium analyzer consists of the following devices:
1. Sample processing system
Automatic Batch Preprocessor: Achieve rapid extraction and preparation of samples, such as using dilute acid rapid extraction method, which can extract lead and cadmium elements from grain samples (such as rice, wheat, corn) within five minutes. This system reduces manual operation steps and improves efficiency.
Sample adding device: including sample tray, sample adding device and other components, used to accurately transfer the test sample to the detection position. Some models support the use of closed reagents, omitting complex pre-processing procedures.
2. Check the core module
Fixed channel graphite furnace atomic absorption device: using graphite furnace as a high-temperature atomizer, quantitative analysis of lead and cadmium elements is carried out through the principle of specific wavelength light absorption. This design supports simultaneous measurement of two elements, improving detection speed.
Light source and optical system: equipped with composite lamps (such as two elements combined into one lamp), combined with slit automatic selection function and full spectrum high-sensitivity array multi pixel CCD solid-state detector, to ensure the accuracy and stability of signal acquisition.
3. Control system and interactive interface
Intelligent control unit: Built in computer system and touch screen operation panel, users can easily call preset methods and quickly execute experiments with just one click. The system also supports real-time monitoring, storage, and printing of data.
Automated mechanical structure: including conveyor belts, mixers, and other components to achieve automatic transmission and mixing of samples between modules, reducing human errors.
4. Auxiliary components
Drainage and cleaning system: Pre drainage design facilitates the detection of waste liquid conditions at any time; The two-color cup cleaning unit is responsible for cleaning the reaction vessel to avoid cross contamination.
Power and gas management module: Provides stable power supply and integrates optional devices such as argon cylinders to optimize combustion or protect the environment.
Function of automatic lead cadmium analyzer:
1. Efficient batch screening
Suitable for large-scale testing of raw and finished grains by grain supervision departments, with a daily processing capacity of up to 240 samples per device, significantly improving regulatory efficiency. Its automated process shortens the time and cost of traditional manual operations.
2. Accurate quantitative analysis
The detection limit of lead method is as low as 0.02mg/kg, and the detection limit of cadmium method reaches 0.002mg/kg, meeting strict food safety standards. The test data has strong stability and provides reliable basis for quality control.
3. Simplify the operational threshold
No experience in chemical analysis is required to complete the entire process, with standardized methods and support for one click startup. Intelligent design reduces reliance on professionals and is suitable for widespread application in grassroots laboratories.
4. Multi domain applicability
Not only used for testing grains and grain products, but can also be extended to raw material acceptance in food processing enterprises, quality monitoring in the production process, and analysis of trace elements in human blood in the medical field.
5. Health and safety optimization
Low acid design reduces the risk of exposure to harmful chemicals and ensures the occupational health of operators; Closed reagent management and automated processing also avoid the possibility of sample contamination.
6. Data management and traceability
The built-in data recording function can generate detailed reports for easy traceability of test results and establishment of databases, facilitating long-term monitoring and trend analysis.
