Product Description
RS 232 double beam aas atomic absorption spectrophotometer
Atomic absorption spectrometer, also known as atomic absorption spectrophotometer, analyzes metal elements according to the effect of ground state atomic vapor on characteristic radiation absorption. It can determine trace elements sensitively and reliably.
Atomic absorption spectrophotometer is generally composed of four parts, namely light source (monochromatic sharp line radiation source), sample atomizer, monochromator and data processing system (including photoelectric converter and corresponding detection device).
Features
1. Buildin computer data processing and LCD: adopting highly integrated micro digital circuit, which is stable and reliable.
2. Good basic line stability: Double-beam system of optimized design can automatically compensate the lights.
3. High precision of measurement: Gas path system is equipped with precision pressure stabilizing and current stabilizing devices to reach stable flame and low noise.
4. Optical path of high energy: A total reflection system is adopted to eliminate color difference in full range.
5. Long-life and anti-corrosive atomization system: The burner is made of new type titanium alloys, anti-corrosive and fast thermal equilibrium.
6. Multifunctional analysis mode: for methods of flame absorption, flame emission, graphite furnace atomic absorption and hydride generation.
7. Safe and reliable gas path system: Special devices of quick gas conversion and safety protection can be used to analyze air-acetylene flame.
