Product news

Just in time with the Analytica 2012 Analytik Jena has announced completely new application options of the contrAA® product series: The simultaneous evaluation of several absorption lines in the measured spectral range is now 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 atomization.

An example for the application is the simultaneous determination of Ni, Fe and V in waste water. Very low vanadium concentrations in the µg/L range can be determined in process waste water along with Ni and Fe concentrations in the mg/L range. The sample throughput can be tripled when measuring samples simultaneously.

The contrAA® series is based on the innovative High-Resolution Continuum Source AAS (HR-CS AAS). It offers all atomization 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, sulfur 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 for non-metal determination with excellent detection limits and minimum sample preparation.

Atomic Absorption / Emission SpectroscopyAtomic absorption spectroscopy (AAS) and atomic emission spectroscopy (AES) — also called optical emission spectroscopy (OES) — are used to detect the elemental constituents in samples. Both techniques involve the atomization of a sample. Atomic absorption spectrometers may use a flame or furnace to create an atomic vapor of the sample before irradiation with spectral light. Optical emission spectrometers may use a flame, inductively coupled plasma (ICP), microwave plasma (MP) or spark arcs to atomize and excite the sample. At higher excitation energies, electrons can be emitted instead of photons, which can be useful for samples that can’t be atomized and for surface analysis. Explore electron spectroscopy equipment such as Auger spectrometers and photoelectron spectrometers for surface elemental analysis of samples.
