DW-AA320N – Atomic Absorption Spectrophotometer
Reference
- DW-AA320N : Atomic Absorption Spectrophotometer
Features
- Built-in computer and LCD display: Integrated data processing ensuring stability and reliability. Functions include integral holding, peak height and area measurement, auto zero adjustment, deuterium lamp background correction, multi-linear and nonlinear curve fitting, display of parameters and calibration curves on screen, and report printing. Interface for external PC connection.
- Excellent stability: Double-beam system automatically compensates for light source and wavelength drift due to temperature variations and electronic drift, ensuring high baseline stability.
- Fast analysis: Hollow cathode lamp requires no long preheating. Samples can be analyzed immediately, ideal for multi-element rapid analysis.
- High measurement precision: Gas path system equipped with pressure and current stabilizers to maintain a stable flame and low noise. Finely focused light beam passes through the flame for high-precision analysis and low characteristic concentration.
- High-energy optical path: Total reflection system eliminates chromatic aberration across the full spectrum. Light beam is converted to an elongated spot optimizing slit passage and increasing double-beam flux.
- Durable and corrosion-resistant atomization system: Burner made of new titanium alloy, corrosion-resistant and thermally stable, no water cooling required, providing excellent measurement sensitivity.
- Multi-functional analysis modes: Flame atomic absorption, flame emission, graphite furnace atomic absorption, and hydride generation.
- Safe and reliable gas system: Quick gas switching and safety devices enable use of air-acetylene and nitrous oxide-acetylene flames, analyzing over 60 elements.
- Complete accessories: Supplied with the instrument, ready to use upon installation.
