Atomic Absorption Spectrophotometer DW-AA320N
Features:
- Built-in computer data processing and LCD display: stable and reliable with the functions of integral holding, peak height and area, auto zero adjusting, deuterium lamp background correction, multi-linear and nonlinear curves fitting, various parameters and working curves displayed on screen and report printing, etc. It is equipped with an interface for externally linking a PC.
- Stability: The double-beam system automatically compensates for light source drift and wavelength drift caused by temperature variations, ensuring good baseline stability. It also handles electronic circuit drift effectively.
- Speed: The cathode lamp does not require long pre-heating time, allowing samples to be analyzed immediately. Ideal for multiple element analysis and fast sample testing.
- High Precision: The gas path system includes precision pressure and current stabilizing devices to ensure a stable flame and low noise. A specially designed fine light beam passes through the flame for high precision and low characteristic concentration.
- High Energy Optical Path: A total reflection system eliminates color differences across the full range. Chemical conversion turns a round light spot into a long one, enhancing the double-beam light flux.
- Long-Life and Anti-Corrosive Atomization System: The burner is made from new titanium alloys, offering corrosion resistance and rapid thermal equilibrium, meeting sensitivity requirements without water cooling.
- Multi-Functional Analysis Mode: Supports flame absorption, flame emission, graphite furnace atomic absorption, and hydride generation methods.
- Safe Gas Path System: Includes quick gas conversion and safety protection devices for air-acetylene and nitrous oxide-acetylene flames, expanding analytical elements beyond 60.
- Complete Accessories: All necessary components are included, ready for immediate use upon purchase.
