The contrAA® series exceeds the performance of conventional AA spectrometers in all parameters.
contrAA® 300, the high-resolution continuum source AAS for flame and hydride technology.
contrAA® 700, a compact, versatile system for flame, hydride and graphite furnace technology, capable of analyzing liquid as well as solid samples in one single instrument.
Persuasive performance characteristics:
Just one light source for all elements
Sequential multi-element analysis as standard
Unique simultaneous background correction
High sample throughput
Rapid readiness for measurement
Easy to operate and robust
New information content
Improved analytical performance
Only One Light Source
With only one light source for all elements and all available wavelengths, the instrument is ready to measure at all times. The previous dependence of the measurement on hollow cathode lamps is eliminated and the associated costly preparation time no longer applies. The protracted burn-in time of the light source, necessary for conventional line sources, is now also no longer required, since any drift phenomena are corrected simultaneously.
Unique Resolution
The unique resolution with a spectral bandwidth of below 2 pm/ pixel is decisive for the new quality of the measurement results. Interference is minimized through optimum line separation. Errors, which were caused by the limits of the resolution in traditional line AAS, can be identified for the first time and thereby avoided.
Solid Sampling
With the contrAA® 700, the direct analysis of solids by AAS has now become a real alternative for many applications. The user is no longer limited to trace analysis, because insensitive lines can also be used without problems. Moreover, the method overcomes the limits of Zeeman AAS with respect to background correction.
