Atomic absorption spectrophotometer SP-3530AA is widely used in various fields such as petrochemicals, environmental sanitation, metallurgy and mining, materials, geology, food, medicine, etc. It has good stability, built-in background correction mode, high sensitivity, easy operation, and can ensure the accuracy of experimental data.

Quick automatic switching, multi-directional safety protection, self inspection of graphite tube installation.

SP-3530AA is a single beam, total reflection achromatic optical system that ensures the unity of various elements in the sample channel and reference channel at different wavelengths, keeping the beam imaging and signal-to-noise ratio at a stable level. After changing the lamp, there is no need to adjust the focus point position, which improves the accuracy, reliability, and work efficiency of the test results.

The super strong anti atomizer light radiation ability can effectively eliminate flame background emission and strong light radiation from 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.

Gap control lamp technology makes it possible to use ordinary hollow cathode lamps for self-priming background correction, extending the service life of the lamp by more than ten times, while the cost is only one tenth of that of dedicated self-priming lamps, greatly reducing the cost of use.
