4ZCA-1000Design features of standard atomic absorption spectrophotometer
1. Total reflection optical system, full band chromatic aberration reduction. After adjusting the focal point, any wavelength can be changed, and the focal point will no longer change. The wavelength will be automatically scanned and peak searched.

2. Featuring deuterium lamp buckle background and self-priming buckle background.

3. The uniquely designed all titanium burner has smooth combustion and fast thermal equilibrium speed.

4. Automatically adjust negative high voltage, lamp current, element lamp position to maximize energy, and automatically protect against gas leakage and flameout.3Support hollow cathode lamp holder. Automatic control system, capable of automatically scanning wavelengths.1Preheat one element lamp and preheat the other two element lamps.

5. Graphite furnace heating: Users can freely set the heating curve according to their needs.
