BK-AA320N | Dual-beam atomic absorption spectrophotometer

Key Features

• High energy optical path
• Long-life and anti-corrosive atomisation system
• Built-in computer data processing and LCD display.
• Double-beam system automatically compensates the light source drift and wavelength drift caused by the variation of temperature and electronic circuit drift
• Cathode lamp does not need to be pre-heated for long time so sample can be analyzed immediately
• Gas path system is equipped with precision pressure stabilising and current stabilising devices to reach stable flame and low noise. Specially designed fine light beam passes through the flame to ensure a high precision analytical test and low characteristic concentration.
• Multi-functional analysis mode:  Flame absorption | Flame emission | Graphite furnace atomic absorption | Hydride generation
• Safe and reliable gas path system: Special devices of quick gas conversion and safety protection can be used to analyze air-acetylene flame as well as nitrous oxide-acetylene flame and extend the analytic elements to reach more than 60.
