Introduction: SP-3887AA Zeeman atomic absorption spectrophotometer is an integrated Zeeman single graphite furnace atomic absorption spectrophotometer. The outstanding performance of the SP-3887 instrument is: innovative in key technologies such as graphite furnace DC power supply transverse heating technology, automatic compensation of graphite furnace resistance change technology, transverse variable AC magnetic field Zeeman background correction technology, self-absorption background correction technology and other key technologies , This product is a graphite furnace integrated machine, which can better detect small signals of high-background samples, and can also directly detect high-temperature elements, and has a wider application prospect. The instrument can be widely used in food, medicine, environment, biology, agriculture, petrochemical, construction, materials, geology, metallurgy, scientific research and other fields. Given that the instrument has excellent AC, DC Zeeman background and deuterium lamp background correction capabilities, the background correction system can not only correct the traditional molecular absorption and particle scattering background, but also correct the structural background and part of the spectral line overlap interference. It is especially suitable for use in the field of trace element analysis and inspection of samples such as food, Chinese medicinal materials, seawater, blood, biological products, and high-salt solutions. Especially for elements that must be analyzed daily, such as Cd, Pb, Cu, Zn, etc., the calibration performance can be comparable to the imported Zeeman instrument, but the instrument price is only 1/2 of the imported Zeeman instrument. Technical features: 1. Double detector optical double beam, total reflection achromatic optical system; 2. The super strong light radiation ability of the antigenizer can effectively eliminate the strong light radiation of the graphite tube under high temperature. 3. Intelligent stray light measurement and correction technology. It effectively improves the optical accuracy and linear range of the atomic absorption spectrometer, and improves the background correction ability. 4. Optical noise reduction technology, combined with ultraviolet enhancement technology of optical components, effectively improves the optical performance and linear range of the instrument. 5. The gap control lamp technology enables ordinary domestic hollow cathode lamps to be used for self-absorption background correction, and the service life of the hollow cathode lamps is extended by more than ten times, reducing the use cost. Horizontal Zeeman (Zeeman) magnetic field longitudinal heating graphite furnace 6. It adopts an eight-light stand system with the light source emission direction parallel to the center of gravity, and the lights are automatically changed. 7. With deuterium lamp, self-absorption, Zeeman (Zeeman) three background deduction methods; 8. Wavelength range: 180nm-900nm automatic peak search 9. Spectral bandwidth: 0.1nm, 0.2nm, 0.4nm, 0.7nm, 1.4nm, 2.0nm six gears automatically switch 10. The position of the graphite furnace atomizer's horizontal, vertical and indexing positions are all free of adjustment;
