DSHX-6 Flame Zeeman Atomic Absorption Spectrometer

I.Features

1.This is a kind of Zeeman background correction AAS which used

Zeeman detection system designed by ourselves (patent No.: 27523).
2.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.
3.Double beam of light atomic absorption, the system is composed by

two via as sample and parameter ratio.
4.Using high sensitivity photo multiplier.
5.Auto-wavelength setting,auto-lamp current,auto-negative voltage and
auto-regulation of energy.
6.Auto water line alarm.
7.Acetylene and air auto-protection device.
8.Can equip hydride generator.
9.Circuit is used by Modular configuration, maintained conveniently.
