AAS 6000 Flame Atomic Absorption Spectrometer
Flame atomic absorption is applied to micro and trace metallic elements test, covering over 30 elements. The instrument has simple structure, provides fast test, with good repeatability and less interference, especially suitable for testing Cu, Zn, K, Na, Au, Ag, etc.
AAS8000 Graphite Furnace Atomic Absorption Spectrometer
Graphite furnace atomic absorption is suitable for trace and ultra-trace metallic elements test, covering over 60 elements. It is highly sensitive, with low limit of detection and less sample volume, especially suitable for testing Cd, Cr, Pb, Al, Mo, etc.
AAS 8000 (with graphite furnace auto sampler) and AAS 8000-M (without graphite furnace auto sampler) are of low detection limit, highly sensitive and easy to operate.
AAS 9000 Integrated Atomic Absorption Spectrometer
It has flame and graphite atomizers, incorporating their features. Users can switch atomizer quickly based on test needs to ensure best test effect.
AAS 9000 (with graphite furnace auto sampler) and AAS 9000-M (without graphite furnace auto sampler) adopt flame and graphite atomizers, with better universality. In serial light path design, it realizes automatic switch between two atomizers, and delivers stable and reliable test.
