Features
This is a kind of Zeeman background correction AAS which used Zeeman detection
     system designed by ourselves (patent No.: 27523).
It has higher detection efficiency, better signal and noisy ratio, therefore, the
     instrument with Zeeman system is better than same kind of instrument in the world
     on sensitivity、detection limit and relative standard deviation.
Double beam of light atomic absorption, the system is composed by two via as
     sample and parameter ratio.
Using high sensitivity photo multiplier.
Auto-wavelength setting、auto-lamp current、auto-negative voltage and
     auto-regulation of energy.
Auto water line alarm.
Acetylene and air auto-protection device.
Can equip hydride generator.
Circuit is used by Modular configuration, maintained conveniently.
