240Z AA and 280Z AA

Zeeman Atomic Absorption Spectromters


The best detection limits of any Zeeman spectrometer

    Based on the sensitive AC-modulated Zeeman technique, proven to give the best detection limits of any Zeeman spectrometer, the 240Z AA, with up to 4 fixed lamp positions, and the 280Z AA, with up to 8 fixed lamp positions, offer the highest sensitivity, performance, simplicity of operation, and industry-leading software in atomic spectroscopy. Both instruments are supplied with the GTA 120 Zeeman graphite tube atomizer for superior graphite furnace performance. Each is controlled by our acclaimed Windows-based Worksheet software.




    Features

  • Enhanced detection limit performance—For ultra trace-level detection limits, plug in high-intensity UltrAA lamps. No additional power supply is required.
  • Optimized performance— PC-controlled magnetic field strength can be varied from 0.1–0.8 Tesla; the field strength remains locked during measurement, minimizing effects of mains voltage variations.
  • Versatility—Add the VGA for Zeeman adaptor and the hydride generation technique to validate Zeeman graphite furnace AA results; offers the flexibility to analyze difficult matrices.
  • Outstanding performance at ppb levels with the Constant Temperature Zone furnace design
  • Easy alignment—Only a single light source is required.
  • 11-fold improvement in correction accuracy—Polynomial interpolation provides superior accuracy over competing systems that use simple linear interpolation (bracketing).
  • Develop optimum analysis conditions with the SRM Wizard and Tube-Cam—Drying, ashing and atomization temperatures, modifiers, injection volumes ensure high sensitivity, free from interferences.
  • Choose the best furnace application based on the distinct characteristics of 240Z AA vs 280Z AA performance
