Product news

Since its introduction into the market, High-Resolution Continuum Source (HR-CS) AAS has revolutionized the world of spectroscopy. contrAA® instruments provide this technology for Flame, Graphite Furnace and Hydride analysis, including solid AA®.

With the latest technical and software upgrades HR-CS AAS becomes even more powerful. Now also simultaneous evaluation of multiple element wavelengths is possible. The Xenon lamp is a continuous radiation source which allows the use of any wavelength. This enables non-metals and "classical" AAS elements to be analyzed together in the same run.

A CCD detector displays the absorption spectrum of samples. AAS users can really see what they are measuring, not only a numeric absorbance value! Moreover spectrum display and comprehensive correction functions allow users to correct any background and spectral interference easily. Together with its software the contrAA® provides analysts from routine and research laboratories with a powerful tool to boost their lab's performance. An easy to use interface ensures simple and convenient operation.

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.

Techniques like ICP-MS, X-ray fluorescence, and atomic absorption spectroscopy allow precise quantification of elements such as metals and nonmetals in complex matrices.
