AA-7050D Atomic Absorption Spectrophotometer

The AA-7050D employs a dual-beam total reflection optical path system, which can automatically perform zeroing, scanning, lamp position adjustment, mirror position adjustment, and energy balancing based on conditions such as the element wavelength selected in the method. It can be widely applied in fields such as metallurgy, petrochemicals, geology, medicine, environmental protection, scientific research, agriculture (soil and fertilizer), disease control, food, materials science, and commodity inspection. Currently, it can analyze more than 70 elements and plays an extremely important role in trace and ultra-trace elemental analysis.
