EWAI AA-7095 Atomic Absorption Spectrophotometer
The EWAI AA-7095 Atomic Absorption Spectrophotometer is an advanced analytical instrument designed for elemental analysis, including trace-element measurement in samples with complex matrices and significant background interference.
Featuring a fixed eight-lamp holder, a transversely heated graphite furnace, and dual background correction technologies, the AA-7095 supports analytical applications requiring reliable measurements and efficient multi-element workflows.
Key Features
- Fixed 8-Lamp Holder: Accommodates eight lamps with simultaneous preheating to help reduce waiting time between analyses.
- Transversely Heated Graphite Furnace: Designed for graphite-furnace atomic absorption analysis.
- Dual Background Correction: Combines longitudinal AC Zeeman and deuterium (D₂) lamp background correction modes.
- Automatic Spectral Bandwidth Selection: Six settings—0.1, 0.2, 0.4, 0.7, 1.0, and 2.0 nm.
- Automatic Slit-Height Switching: Automatically adjusts slit height according to analytical requirements.
- Automatic Peak Search: Performs zero return, wavelength scanning, lamp positioning, mirror adjustment, and energy balancing automatically.
