Saving measurement time:  Simultaneous multi-element determination with High-Resolution Continuum Source AAS (HR-CS AAS) in graphite furnace and flame 

New application options of the revolutionary contrAA® product series: The simultaneous evaluation of several absorption lines in the measured spectral range is now also possible. This is a particular advantage in the relatively time-consuming graphite furnace technique, because it is possible to determine several elements with just one atomisation.

An example for the application is the simultaneous determination of Ni, Fe and V in wastewater. Here, very low vanadium concentrations in the µg/L range were determined in the process wastewater along with Ni and Fe concentrations in the mg/L range. The sample throughput can be tripled when measuring samples simultaneously. The three-dimensional spectra supports the user in optimising the atomisation parameter.

The contrAA® series is based on the innovative High-Resolution Continuum Source AAS (HR-CS AAS). It offers all atomisation techniques, including the direct solids analysis with solid AA®. In addition to the traditional use for the determination of various metals, the contrAA® opens up a completely new field of application: The determination of non-metals, e.g. halogens, sulphur and phosphorus, by means of characteristic molecule absorption bands in flame and graphite furnace. This makes the HR-CS AAS an easy, fast and reliable method also for non-metal determination with excellent detection limits and minimum sample preparation – a real alternative to all previously available analysis methods.
