Blood lead and cadmium analyzer

(graphite furnace atomic absorption spectrometry)

A special medical instrument for measuring the contents of lead and cadmium in human body by atomic absorption graphite furnace analysis technology.

Compared with conventional atomic absorption spectrophotometer, it has the characteristics of fast, simple operation, synchronous measurement, etc., which improves the analysis efficiency of atomic absorption and reduces the labor intensity of analysts. It is a detection method recognized by international authoritative departments, so it has excellent cost performance.

1. After 40 μ l blood is added into the diluent, lead and cadmium can be detected at the same time, and the detection can be completed in 1-2 minutes;

2. The use of closed special reagents can omit the complicated pretreatment process of samples and reduce the pollution to samples and operators;

3. The two elements are combined into one lamp, and the two elements are detected at the same time, which makes the analysis work convenient and fast;

4. The volume of products in the same industry is the smallest;

5. Graphite furnace atomization technology has greatly improved the accuracy and precision of analytical results; Internationally recognized blood lead and cadmium detection methods;

1. Baseline noise: the maximum instantaneous noise within 30min shall not be greater than 0.005abs

2. Repeatability: the relative standard deviation of lead and cadmium shall not be greater than 4%

3. Detection limit: the detection limit of lead is 5 µ g/l; The detection limit of cadmium is 0.2 µ g/l.
