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.
With a Xenon lamp emitting a continuous spectrum at high intensity, any element and wavelength can readily be analyzed whenever the requirement occurs – the contrAA® turned AAS into a true multi-element technique with unmatched flexibility. A high-resolution spectrometer with CCD detector produces a highly resolved absorption spectrum for each sample, providing deeper insight about the sample as well as visual proof of correct signal evaluation.
With features like fast sequential and simultaneous multi-element analysis, including semi-quantitative overview screening of unknown samples, and analysis of non-metals contrAA® 800 opens up new application fields previously reserved to other, much more expensive technologies. Superior correction algorithms for background and spectral interferences take productivity and accuracy of AAS to a new level – all while preserving its simple, robust and low-cost operation.
With its automatic atomizer switching and two-dimensional atomizer alignment, the contrAA® 800 is a versatile all-rounder that comes in a modern, space-saving design.

Determination of PFAS in soil and sewage sludge as a sum parameter EOF (Extractable organically bound fluorine)
PFAS are per- and polyfluoroalkylated substances with persistent properties, which have therefore been and still are used in everyday objects (e.g., water-repellent coatings for textiles and paper, cookware). Due to their multiple uses, PFAS are currently found in numerous environmental samples. Besides monitoring of surface water or contaminated soils, control at wastewater treatment plants is of increasing interest. Since PFAS are very resistant to conventional biological treatment in wastewater plants, they can not be removed from wastewater without a special treatment step and are therefore often found in the effluent of wastewater treatment plants or in sewage sludge. In this application note, Analytik Jena shows that the quantification of PFAS in different solid samples as a sum parameter can be carried out very quickly and easily with the described EOF method using the contrAA 800.
Determination of trace and minor elements in alloys with solid AA
This application note from Analytik Jena is focused on the analysis of nickel-based alloys.
