SP-3887ZAA Zeeman Graphite Furnace Atomic Absorption Spectrophotometer Introduction
The SP-3887ZAA Zeeman Atomic Absorption Spectrophotometer is a Zeeman single graphite furnace atomic absorption machine.
The instrument can be widely used in food, medicine, environment, biology, agriculture, petrochemical, construction, materials, geology, metallurgy, scientific research and other fields. In view of the excellent AC, DC Zeeman background and xenon backlight correction capability of the instrument, the background correction system can correct the structural background and partial line overlap interference in addition to the traditional molecular absorption and particle scattering background. It is especially suitable for use in the field of trace element analysis and testing for the determination of samples such as food, Chinese herbal medicines, sea water, blood, biological products, and high salt solutions. Features
Dual detector optical double beam, total reflection achromatic optical system;
The superior antigenicizer's light radiation ability can effectively eliminate the intense light 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 enables the ordinary domestic hollow cathode lamp to be used for self-priming background correction, and the service life of the hollow cathode lamp is extended by more than ten times, thereby reducing the use cost.
