8 Cathode Hollow Lamp Automatic Atomic Absorption Machine
Feature
1. Total reflection optical system, full-wavelength achromatic, automatic wavelength scanning, automatic peak finding.
2. The uniquely designed all-titanium burner has stable combustion and fast heat balance.
3. Automatic adjustment of negative high voltage, lamp current, and element lamp position can be adjusted at will to maximize energy, automatic gas leakage and flameout protection.
8 lamp holders (optional 2 high-performance lamps) automatic control system, which can adjust the hollow cathode lamp to the best position in all directions
The lamp position of a specific element can be individually set, and the working lamp and preheating lamp can be set freely to maximize the savings
Element lamp preparation time. . The automatic control system can automatically scan the wavelength.
4. It can be upgraded to a graphite furnace atomic absorption spectrophotometer.
