 Applicable fields:

Food hygiene, geology, metallurgy, agricultural testing, chemical environmental protection, water quality testing, pharmaceutical commodity inspection, education and research, etc.


 Detection elements:

It is mainly used for more than 70 elements such as gold, silver, copper, lead, zinc, manganese, potassium, sodium, calcium, magnesium, iron and cadmium in food, surface water, groundwater, drinking water and other samples.


 Product features:

•Zeeman background correction and full band background deduction.

•Transverse zeeman; constant magnetic field; energy saving and consumption reduction.

•Quasi double beam without preheating.

•Automatic rotating lighthouse; eight lamps can be preheated simultaneously.

•The patented design of slip-ring 8-lamp lighthouse overcomes the rotation and winding of lamp cables.

•Wavelength Range: 190nm~900nm.

•Spectral Bandwidth: 0.2, 0.4, 1.0, 2.0nm(automatic switching).

•C-T optical path design; plane diffraction grating with 1800 lines/mm.

•Focal length: 270mm; short optical path and strong energy.

•Automatic peak setting and automatic spectral bandwidth.

•A variety of self-diagnosis functions, fault detection and other safety functions.

•Windows software in both Chinese and English version has powerful data traceability function. Standard curve method and standard addition method can be selected. With slope reset and curve recalibration functions, the correction curve can be edited, allowing the selection of correction curve and sample blank for correction.

•Integrated design; built-in graphite furnace power supply; 

•Graphite furnace temperature: current and voltage vector control; accuracy is less than 0.5%(2000℃).

•Longitudinal Heating: room temperature to 3000℃; heating rate ≥2000℃/s.

•The patented 64-position sampler adopts high-precision sample pump and cleaning pump and the double injection pumps are used for vertical injection (accuracy≤0.5%(20μL)).

•Automatic preparation of standard solution and automatic dilution.

•Gas pressure monitoring: prevent damage to graphite cone and graphite tube due to lack of protective gas.

•Graphite furnace’s body temperature detection: forbid measurement when the temperature is too high.

•With temperature monitoring of power transformer to prevent damage.

•With graphite tube fracture or unclamp detection to ensure normal measurement.
