contrAA® Series — Atomic Absorption. Redefined.
The atomic absorption spectrometers of the contrAA® series are the only commercially available instruments for High-Resolution Continuum Source AAS (HR-CS AAS). As a link between standard AAS instruments and ICP-OES spectrometers contrAA® combines the best of two worlds: rapid sequential and simultaneous multi-element analysis, ease of handling and manageable costs.
The unique technology of the contrAA® provides significant analytical advantages over the traditional Line-Source AAS. Thanks to the Xenon short arc lamp, that emits a continuous spectrum at high intensity, any element and wavelength can readily be analyzed whenever the requirement occurs. The high-resolution spectrometer with CCD detector produces a highly resolved absorption spectrum for each sample, allowing not only quantitative evaluation of but also qualitative information about the sample.
With features like fast sequential and simultaneous multi-element analysis — including semi-quantitative overview screening of unknown samples, and analysis of non-metals — contrAA® opens up new application fields.
Modern correction algorithms for background and spectral interferences have taken productivity and accuracy of AAS to a new level.
