contrAA 800 F atomic absorption spectrometer

contrAA series atomic absorption spectrometers with linear continuum source

contrAA® 800 F are atomic absorption spectrometers with a linear continuum source and flame atomization. contrAA® series marks a link between conventional AAS and ICP-OES, combines the best qualities of both methods: AAS simplicity and affordability with ICP-OES speed. Just one lamp allows identifying all the elements, metals and non-metals, at any wavelength. The optical system and the CCD detector create a high-resolution absorption spectrum for each sample, which provides exhaustive information about the latter. Spectrum display in 3D format drastically facilitates development of the method.

Main advantages:

one light source for fast sequential multi-element analysis w/o lamp change, heating, and adjustment;
expanded measurement range up to the fifth order;
semiquantitative analysis of unknown samples of metals and non-metals;
3D visualization of spectra to identify complex analytical lines in high resolution;
high resolution optics for low noise level, precision and low detection limits;
state-of-the-art background correction and spectral overlap algorithms;
automatic dosed introduction of samples into the flame with the smart dilution feature;
continuous batch-wise injection of microsamples into the flame using a segmented flow star (SFS).
