Instrument Introduction:

SP-3887AA Zeeman Atomic Absorption Spectrometer

For the Zeeman single graphite furnace atomic absorption machine.

The outstanding performance of SP-3887 instrument includes:
Innovative in key technologies such as graphite furnace DC power supply lateral heating technology, automatic compensation of graphite furnace resistance change technology, lateral variable AC magnetic field Zeeman background correction technology, self-priming background correction technology, etc,
This product is a graphite furnace integrated machine that can effectively detect small signals from high background samples and directly detect high-temperature elements, with a wide range of application prospects.

Application areas and purposes:
The instrument is positioned in the mid-range upper price range and performance, with multiple different configurations to meet the needs of different users. The price ranges from 250000 yuan to 450000 yuan. Instruments can be widely used in fields such as food, medicine, environment, biology, agriculture, petrochemicals, construction, materials, geology, metallurgy, and scientific research. Given the excellent AC and DC Zeeman background and deuterium lamp background correction capabilities of the instrument, this background correction system can not only effectively correct traditional molecular absorption and particle scattering backgrounds, but also correct structural backgrounds and partial spectral line overlap interference. It is particularly suitable for the analysis and testing of trace elements in samples such as food, traditional Chinese medicine, seawater, blood, biological products, and high salt solutions. Especially for daily essential elements such as Cd, Pb, Cu, Zn, etc., the calibration performance can be comparable to imported Zeeman instruments, but the instrument price is only half of that of imported Zeeman instruments, which will be more suitable for China's national conditions.

Dual detector optical dual beam, total reflection achromatic optical system;

The super strong anti atomizer light radiation ability can effectively eliminate the strong light radiation of graphite tubes at high temperatures.

Intelligent stray light measurement and correction technology, Effectively improved the optical accuracy and linear range of the atomic absorption spectrometer, and enhanced its background correction capability.

Optical noise reduction technology, combined with optical component ultraviolet enhancement technology, effectively improves the optical performance and linear range of the instrument.
