280Z AA Atomic Absorption Spectrometer

Description

The Agilent 280Z AA is a double-beam atomic absorption spectrometer utilizing AC-modulated Zeeman background correction. It operates across a wavelength range of 185 to 900 nm and is equipped with a single light source capable of holding up to eight fixed lamp positions, accommodating both hollow cathode and high-intensity UltrAA lamps. The instrument is typically supplied with the GTA120 graphite tube atomizer, which employs a constant temperature zone furnace design for consistent performance. A key feature is the software-controlled variable magnetic field, adjustable from 0.1 to 0.8 Tesla, which remains stable during measurements to minimize interference from power fluctuations. The system's software uses polynomial interpolation for enhanced correction accuracy and includes tools like an SRM Wizard and Tube-CAM to assist in developing optimal furnace temperature programs and method parameters. This configuration is intended for ultra-trace-level analysis, offering high sensitivity and the flexibility to handle complex sample matrices.
