Atomic Absorption Spectrophotometer

Atomic Absorption Spectrophotometer  
 
The Atomic Absorption Spectrophotometer is fully PC controlled. It can be flexibly equipped with optional graphite furnace,

auto sampler and hydride generator. Unique optical mechanical design, safe and convenient flame system, optional background

correction technologies, as well as convenient functions provided by the workstation, suit your pursuit of automatic and precise test results.

 

Features:          
1. Excellent total reflection optical system ensures excellent signal-to-noise ratio of the instrument.
2. Comprehensive and safe intelligent gas control module.
3. Excellent full band deuterium lamp background correction technology and high-performance self absorption double background correction.
4. Fully automatic instrument control, light source supports high-performance element lamp, and can be completed quickly with one key.
5. Original lamp position eight lamp holder 360 degree rotation design.
6. Novel atomizer and intelligent elevator.
7. Simple, professional, automatic and fully operated RG WIN AAS workstation software under MS window system.
