Varian SpectrAA 220Z Atomic Absorption Spectrophotometer

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, AC modulated Transverse 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 without requiring complex optimization of the field strength.

Productivity in the laboratory is also improved with the use of Varian’s award winning multi-tasking Worksheet software. This advanced software combines the familiar spreadsheet concept with the full multi-tasking capabilities of the Windows operating system.

A fully automated double beam system with Zeeman operation for improved productivity. Enhanced capabilities, including full PC control and automated operation as standard. The SpectrAA 220 optics feature four lamp positions with automated wavelength and slit selection, and high intensity deuterium background correction as standard. Lamps are mounted in fixed positions, and a rotating mirror is used to select the operating lamp, eliminating the need for a conventional turret. For maximum stability in an automated sequence, a software controlled next-lamp warm up facility is provided.
