BK-AA320N | Dual-beam atomic absorption spectrophotometer for environmental monitoring, food testing, clinical research, and industrial quality control

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 an extended time so samples 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

Product Description

The BK-AA320N dual-beam atomic absorption spectrophotometer is a valuable tool for analyzing trace metals in various fields like environmental monitoring, food testing, clinical research, and industrial quality control. These capabilities allow it to be used to quantify the presence of individual elements in a solution by analyzing their unique absorption patterns.

The BK-AA320N features a high energy optical path, a long-life and anti-corrosive atomisation system, and built-in computer data processing and LCD display that provides multi-functional analysis capability. The benefit of a double-beam system is that it automatically compensates the light source drift and wavelength drift caused by the variation of temperature and electronic circuit drift. Another benefit of the BK-AA320N is that the cathode lamp does not need to be pre-heated for an extended time so samples can be analyzed immediately.

The safe and reliable gas path system of the BK-AA320N is equipped with precision pressure stabilising and current stabilising devices to reach stable flame and low noise. The specially-designed fine light beam passes through the flame to ensure a high precision analytical test and low characteristic concentration.
