contrAA® 800 D – Your Benefits:

  • 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
  • Rapid readiness for measurement
  • Automatic atomizer change and two-dimensional atomizer alignment
  • Automatically optimized drying process for highly efficient analysis
  • Easy to operate and robust

 

 

Software

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
  • Efficient correction of spectral interferences
  • 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.

Applications

The contrAA® 800 D combines all atomizing techniques in a compact device, making it universally and flexibly applicable. Thanks to the numerous analytical advantages of HR-CS AAS it provides the appropriate solution for almost every field of instrumental analysis, in routine application as well as in research.

contrAA® 800 D is suited for fast-sequential and simultaneous multi-element analysis. The sample throughput for multi-element analysis using flame technique of the new generation of contrAA® meets the level of simultaneous ICP-OES instruments. In graphite furnace technique which offers very low detection limits for many elements the simultaneous multi-element analysis allows a higher throughput than conventional line source AAS.

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 or HydrEA technique contrAA® 800 D can be used for the determination of hydride forming elements, e.g. antimony, arsenic, bismuth, selenium, or tin.
