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 offers the highest sensitivity, performance, simplicity of operation and industry-leading software in atomic spectroscopy. The instrument is supplied with the GTA 120 Zeeman graphite tube atomizer for superior graphite furnace performance and is controlled by our acclaimed Windows-based Worksheet software.
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 to 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.
