High-Resolution Continuum Source AAS - redefining AAS

The new technology - High-Resolution Continuum Source AAS - represents previously unattained effectiveness and quality of measurement results. The contrAA series combines intelligent design with persuasive performance characteristics: just one light source for all elements, sequential multi-element routine as standard, unique simultaneous background correction, high sample throughput, rapid readiness for measurement, easy to operate and robust, new information content, improved analytical performance.

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.

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.
