Combined flame and graphite furnace atomic absorption spectrometer (F-AAS/GF-AAS) Analytik Jena
contrAA - HR-CS AAS

The series comprises two instruments:
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.

- 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
- Independence of hollow cathode lamps

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. The use of a xenon lamp as a continuous source of radiation opens up the entire wavelength range relevant for AAS for the customer in just one step. Previously, individual methods predominated; now the sequential multielement-routine has become standard. This provides enormous savings in time and cost of materials. The evaluation of molecular absorption bands, allowing the analysis of additional elements, such as sulfur or phosphorus, is a further innovation.

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.
