• Unique flexibility
• Possibility to change quickly from flame technology to graphite furnace technology and vice versa, with only one mouse click! (tandem principle)

Simultaneous analysis of several absorption lines
contrAA enables the simultaneous analysis of several absorption lines in the measured spectral range. This offers great benefits especially in the relatively time-consuming graphite furnace technology, because several elements can be detected simultaneously using a single atomization.

One application example is the simultaneous detection of Ni, Fe and V in waste water. Low vanadium concentrations in the µg/l range are detected in parallel to Ni and Fe concentrations in the mg/l range in process water. Using simultaneous measurement the sample throughput can be tripled. The unique three-dimensional spectrum representation supports users in the rapid optimization of the atomizing parameters without additional empirical intermediate steps.

• Increase of the sample throughput
• Easy optimization of methods

The High-Resolution Continuum Source AAS technology (HR-CS AAS) Now Also Enables the Detection of Non-Metals Using an AAS Instrument

Thanks to a Xenon lamp as continuous radiation source, any wavelength is available for measurement on the contrAA - including molecular bands. By converting the non-metals into characteristic molecules, these can be detected using molecular absorption spectrometry (MAS). HR-CS MAS is a new robust method for the selective analysis of the individual non-metals in aqueous and organic solutions and directly in solids - independent of the type of chemical bonding. Without extensive sample preparation the non-metals in the graphite furnace are converted quantitatively into the target molecule and then detected by way of spectrometry. It does not matter whether the non-metals are free anions or organically or inorganically bound in the sample. Thus a simple, fast and reliable spectrometric method for the detection of non-metals in almost any matrix and across a wide range of concentrations is available for the first time, e.g. of fluorine in water or toothpaste or of phosphorus in animal feed or seepage water.
