Product Details
Atomic absorption spectrometer can be used in the fields of metallurgy, petrochemical, geology, medical science, environmental protection, scientific research, agriculture, disease control, food safety, material science, and quality inspection among others. 
First domestic manufacturer to use an 1800 lines/mm diffraction grating, which increases resolution and energy efficiency.
Optimized lamp power supply technology to prolong lifetime of element lamps.
Safe and reliable control alarming devices to ensure over-current protection for hollow cathode lamps.
Automatic wavelength positioning, automatic slit switch and automatic optimization of lamp current and gain. All of these operations can be completed within 40 seconds.
Auxiliary gas, such as oxygen, can be used in the internal gas path of the graphite furnace to sufficiently remove organic components of the sample during the ashing treatment phase in order to reduce interference and increase analysis accuracy.
Automatically find the optimal flame height for best analysis condition.
Flame ignition is controlled with a combination of a float inside the liquid trap and an electromagnetic valve to avoid acetylene leakage due to lack of water in the liquid trap. This increases operation safety.
