AA-7050D Atomic Absorption Spectrophotometer

AA-7050D adopts double-beam full-reflection optical path system, which can automatically complete zero return, scanning, lamp position adjustment, mirror position adjustment and energy balance according to the element wavelength and other conditions selected in the method. It can be widely used in metallurgy, petrochemical, geology, medicine, environmental protection, scientific research, agriculture (soil fertilizer), disease control, food, materials science, commodity inspection and other fields. At present, it can analyze more than 70 kinds of elements, which has extremely important applications in trace and ultra-trace elemental analysis.
