  As the inventor of the Zeeman technique in the late 1960s, Varian patented all possible Zeeman configurations and chose to adopt the more sensitive AC modulated Zeeman technique. This system has proven to give the best detection limits of any Zeeman spectrometer available. The Zeeman instruments continue to set the industry benchmarks for uncompromised Zeeman performance. The SpectrAA Zeeman instruments offer the highest sensitivity, performance, simplicity of operation and industry leading software expected of a worldwide leader in atomic spectroscopy.

The combination of a Constant Temperature Zone graphite furnace, fast Zeeman background correction and polynomial interpolation ensures superior spectral interference correction and maximum sample accuracy. In addition, Varian's low thermal mass graphite tubes with their long atom cell and fixed 0.8 Tesla AC magnetic field maximizes sensitivity.

The AA280Z has up to 8 fixed lamp positions. It is supplied complete with the GTA120 Zeeman graphite tube atomizer, ensuring superior graphite furnace performance.

Key benefits include:
  • Enhanced detection limit performance
    For ultra trace level detection limits, simply plug in Varian's UltrAA lamps. UltrAA lamps are high intensity boosted discharge lamps that reduce noise and enhance sensitivity, ensuring better (lower) detection limits can be achieved.
  • Optimized performance
    The AA280Z enables the user to optimize the background correction to enhance sensitivity and reduce interferences. To achieve this, the magnetic field strength is PC-controlled over range 0.1–0.8 Tesla. Yet the field strength remains locked during measurement minimizing effect of mains voltage variations.
  • Versatility
    Using the VGA for Zeeman adaptor, you can use the hydride generation technique on the Varian Zeeman instruments. This offers an easy and reliable way of validating your Zeeman graphite furnace AA results, and also offers you the flexibility to analyze difficult matrices.
This Varian AA280Z Zeeman Atomic Absorption Spectrometer with GTA 120 Graphite Tube Atomizer is in great condition.

A 90-day warranty is included.
