contrAA - Model 800 F - High-Resolution Continuum Source Atomic Absorption Spectrometer
contrAA 800 F is the compact High-Resolution Continuum Source atomic absorption spectrometer for flame and hydride technique. It provides fast-sequential and simultaneous multi-element analysis using flame technique in a flexible working range, from traces up to high concentrations. Coupling with the hydride technique enables the determination of hydride-forming elements, such as antimony, arsenic, bismuth, selenium, or tin.
- Just one light source for all elements – each element and each line can be measured at any time
- Unique simultaneous background correction
- Fast-sequential and simultaneous multi-element analysis
- High sample throughput
- Rapid readiness for measurement
- Easy to operate and robust
ASpect CS has been specifically developed for multi-element analysis with the contrAA®. In addition to a fast sequential determination of different elements in one sample several element lines in the spectrum window can be analyzed simultaneously. Automatic optimization routines find the optimum measuring conditions for every application. Automatic correction routines (ABC) provide a simultaneous correction of complex structured background. Spectral interferences are resolved using matrix correction spectra (CSI).
ASpect CS — Your Benefits
- Simultaneous multi-element analysis
- Free definition of the integration range of each line
- Simultaneous background correction

- Easy creation of analytical methods for one or several elements
- Optimization routines for optimal measuring conditions
- Manipulation-protected data storage
- FDA 21 CFR Part 11 compliance
ABC — Automatic Baseline Correction
The unprecedented ABC algorithm for background correction convinces by automatically fitting a global baseline to the entire spectral background. Unlike conventional correction methods, contrAA® allows to visually verify the background correction within the HD Spectrum. Confidence in the measured values is increased as you can see what you measure!
CSI-Software-Tool — Correction of Spectral Interferences
Although spectral interferences are reduced to a minimum due to the high spectral resolution of the contrAA®, sometimes spectral interference caused by matrix elements or molecular bands have to be corrected. The CSI software tool allows for an easy and efficient correction of such interferences. Thanks to its patented least-square algorithm CSI is the most powerful tool for correcting spectral interference, thus improving detection sensitivity, method robustness and productivity of your analytics.

contrAA 800 F is perfectly suited for the fast-sequential or simultaneous multi-element analysis. The sample throughput for multi-element analysis of the new generation of contrAA meets the level of simultaneous ICP-OES instruments.
In addition to the traditional use for the determination of various metals, the HR-CS AAS can also be applied for the analysis of non-metals, such as phosphorus, sulfur or halogens. In connection with the hydride technique contrAA 800 F can be used for the determination of hydride forming elements, e.g. antimony, arsenic, bismuth, selenium, or tin.
The HR-CS AAS can be applied in nearly all fields of instrumental analysis. Thanks to its numerous analytical advantages, for both routine as well as research, it always provides the ideal solution.
