Grain and oil heavy metal quick check solution
Escort for a healthy life
It is mainly used for rapid non-destructive testing of heavy metal elements such as Cd, Pb, As, Cr and Se se in crops such as rice, wheat, brown rice, soybean and tea. There is no need to chemically pretreat samples, powder and granular samples can be tested directly and samples can be quickly screened in minutes.
After the sample is irradiated with X-rays, the electrons in the inner shell of the element are excited to cause an electronic energy level transition, and the characteristic X-ray fluorescence of the element is emitted. Qualitative and quantitative analysis of the elements can be performed by measuring the wavelength and intensity of the characteristic emission X-ray fluorescence of the sample. Taking into account the measurement accuracy and efficiency, the test can be adjusted to the fast screening mode and the accurate measurement mode by setting test conditions such as test time.
1. The instrument is easy to operate, no sample pretreatment, no consumables, and can be used for rapid qualitative and quantitative analysis of Cd in rice and other cereals.
2, the fuselage full lead plate protection, fully guarantee the personal safety of the operators.
3, within 180 seconds to complete the 0.2% screening of Cd element limit value in rice, accurate quantification in 1200 seconds, the sample weight is about 8g.
4. The sample number is identified by a two-dimensional code, and the automatic sample changer does not need to place the samples in numerical order.
5. The auto-changer has dual operation modes of “sample placement in sequence and test function mode” and “sample disorder placement and test function mode”. The QR code information is not scanned in the order of number and in the test function mode, so it is not necessary to print the QR code sticker.
6. Sample spin function: The sample rotates automatically during the test, which can effectively reduce the test deviation caused by uneven sample preparation.
7. The hardware has a linkage-privilege security lock, which can control the device even if the software fails, ensuring the personal safety of the operator during use.
