Product Description

Product Description

Grain Heavy Metal Detector Cadmium element (Cd) detector X-ray fluorescence analyzer HDXRF
1. Product Introduction

T-450 adopts high-precision X-ray fluorescence (HDXRF) technology. By using advanced monochromatic and focusing optical devices, hyperboloid curved optical crystal (DCC), the signal-to-noise ratio of the equipment is greatly improved, making it different from traditional energy-dispersive X-ray fluorescence. The detection accuracy is greatly improved compared to EDXRF technology. Figure 1 shows the basic structure of HDXRF technology equipment. The hyperboloid curved crystal optical crystal (DCC) converts polychromatic light from the radiation source into high-energy monochromatic light and effectively focuses it on the measurement sample. The sample is excited by the focused high-energy monochromatic beam. Afterwards, the heavy metal elements in the sample emit their own characteristic X-ray fluorescence signals. The high-resolution SDD semiconductor detector collects and processes the signals. Finally, the software FP algorithm calculates the element content contained in the sample.

Cadmium Compliance Testing
Based on HDXRFtechnology, T-450 can quickly and accurately quantitatively analyze cadmium and other heavy metal elements in food and grain. Its excellent detection performance can meet the requirements of China's national food safety standards - the detection limit easily meets the regulatory limit of 0.2mg for cadmium in rice. /kg. In addition, T-450 can also perform preliminary screening and qualitative analysis of arsenic in rice.
Quick scan
T-450 is light in weight and small in size, easy to carry, and simple to operate. It does not require complicated sample preparation steps and can easily meet the needs of fast and accurate scanning and analysis at the work site. The results are shown in Table 2.
1. Quick scan in two minutes;
2. Quickly distinguish between excessive, qualified and gray area samples;
Cadmium Compliance Testing

Instrument features
1. No chemical digestion is required, and the test speed is fast;
2. The element detection limit is low and complies with GB2762-2017;
3. Analysis mode: qualitative scanning analysis mode, quantitative analysis mode.
accuracy and repeatability
Select a certain number of rice standard samples, directly analyze the Cd and cadmium elements in them, and examine the testing accuracy of the instrument by analyzing the relative error between the measured value and the standard value. The data in Table 3 shows that HDXRF can provide accurate and stable results in the detection of high and low cadmium content. The analysis error of 0.2 and 0.1 mg/kg samples is usually less than 10%.
