SP-3590AA Atomic Absorption Spectrophotometer Introduction
Atomic absorption spectrophotometer SP-3590AA is widely used in petrochemical, environmental sanitation, metallurgical mining, materials, geology, food, medicine and other fields. The stability is good, the background correction mode is adopted, the sensitivity is high, the operation is simple, and the accuracy of the experimental data can be guaranteed.
Feature
Fast and automatic switching, multi-directional safety protection, graphite tube installation self-test.
The single-beam, total reflection achromatic optical system ensures the uniformity of the two beams of the sample channel and the reference channel at different wavelengths, so that the beam imaging and signal-to-noise ratio are at a stable level, and there is no need to adjust the position of the focus point after the lamp is replaced. Improve the accuracy, reliability and efficiency of test results.
The superior antigenicizer's light-radiating ability can effectively eliminate the background emission of the flame and the intense optical radiation of the graphite tube at high temperatures.
Intelligent stray light measurement and correction technology. It effectively improves the optical precision and linear range of the atomic absorption spectrometer and improves the background correction ability.
Optical noise reduction technology, combined with optical component UV enhancement technology, effectively improves the optical performance and linear range of the instrument.
The gap control lamp technology makes it possible to use the common hollow cathode lamp for self-priming background correction. The service life of the lamp is extended by more than ten times, and the cost is only one tenth of that of the dedicated self-priming lamp, which greatly reduces the use cost.
Longitudinal heating of graphite furnace technology
It adopts a vertical 8-lamp system with ground, automatic light change, and two-dimensional automatic fine-tuning of the light stand.
