Automatic Background Separation
The contrAA^® is the first AAS capable of separating broadband and spectral background effects. The former are corrected automatically over the reference pixels and the latter are rendered visible and can be evaluated. In most cases of spectral interferences, however, the outstanding resolution is sufficient, so that the analysis line can be used for the evaluation without modification.

We aim to contrAA^® users an unmatched background correction, thus enormously improving the measurement quality.

3D Spectroscopy for more Information Content
The entire environment of the analysis line can be observed in high resolution using this technique. Conventional measurement of absorbance over time is supplemented by a third dimension - wavelength. This three-dimensional spectroscopy offers unimagined possibilities for optimizing parameters, during method development and for identifying and preventing spectral interference. Until now, only the results of any spectral interference became visible. Now however, with HR-CS AAS, the user can identify the cause of this interference and eliminate it, as required.
