Atomic Absorption Spectrophotometer DW-AA320N
Features:
- Integrated computer data processing and LCD display for stable and reliable operation. It supports functions such as integral holding, peak height and area measurement, auto zero adjustment, deuterium lamp background correction, multi-linear and nonlinear curve fitting, parameter display, and report printing. The device is equipped with an external PC interface.
- Double-beam system ensures stability by automatically compensating for light source drift, wavelength drift, and electronic circuit drift caused by temperature changes. This results in excellent baseline stability.
- Quick analysis without the need for long preheating of the cathode lamp, allowing immediate sample analysis. Ideal for multi-element analysis and fast sample testing.
- High precision measurement with a gas path system that includes pressure and current stabilizing devices for stable flame and low noise. A specially designed fine light beam passes through the flame, ensuring high analytical accuracy and low characteristic concentration.
- High-energy optical path using a total reflection system to eliminate color differences across the entire range. Chemical conversion transforms the round light spot from the light source into a long one, enhancing double-beam light flux.
- Long-life and corrosion-resistant atomization system made from advanced titanium alloys. It offers fast thermal equilibrium and meets sensitivity requirements without water cooling.
- Multi-functional analysis modes include flame absorption, flame emission, graphite furnace atomic absorption, and hydride generation.
- Safe and reliable gas path system with quick gas conversion and safety protection features, enabling analysis of air-acetylene and nitrous oxide-acetylene flames, expanding the number of analyzable elements to over 60.
- Complete set of accessories provided, ready for use upon purchase.
