2、 Standard configuration
1. Host
2. Low noise oil-free air compressor
3. Hollow cathode lamp
4. Operating software
3、 Design Features of ZCA-1000AF Fully Automatic Flame Atomic Absorption Spectrophotometer
1. Total reflection optical system, full band chromatic aberration reduction, automatic wavelength scanning, and automatic peak searching.
2. The uniquely designed all titanium burner ensures smooth combustion and fast thermal equilibrium speed.
3. Automatic adjustment of negative high voltage, lamp current, optimal element lamp position, automatic ignition, and automatic shutdown protection. The automatic control system of the 8-lamp rack (optional with 2 high-performance lamps) can adjust the hollow cathode lamp to the optimal position in all directions, and can set the position of a specific element lamp separately. The work lamp and preheating lamp can be freely set to save the preparation time of the element lamp to the greatest extent possible.
4. It can be upgraded to a graphite furnace atomic absorption spectrophotometer.
