contrAA 800 D atomic absorption spectrometer

contrAA series atomic absorption spectrometers with linear continuum source

contrAA® 800 D are atomic absorption spectrometers with a linear continuum source, flame and electrothermal atomization in graphite furnace. contrAA® atomic absorption spectrometers mark a link between conventional AAS and ICP-OES, combine the best qualities of both methods: AAS simplicity and affordability with ICP-OES speed. Just one lamp allows identifying all the elements, metals and non-metals, at any wavelength. The optical system and the CCD detector create a high-resolution absorption spectrum for each sample, which provides exhaustive information about the latter. Spectrum display in 3D format drastically facilitates development of the method.

Main advantages:

• one light source for fast sequential multi-element analysis w/o lamp change, heating, and adjustment;
• a pyrometer for non-contact accurate online measurement of temperature;
• expanded measurement range up to the fifth order;
• semiquantitative analysis of unknown samples of metals and non-metals;
• 3D visualization of spectra to identify complex analytical lines in high resolution;
• high resolution optics for low noise level, precision and low detection limits;
• analysis of hard-melting elements already at atomization temperature of 2600°C;
• transverse heated graphite furnaces and current supply via integral contacts;
• monitoring of dosing and atomization processes in the furnace with the aid of a video camera;
• state-of-the-art background correction and spectral overlap algorithms;
• automatic dosed introduction of samples into the flame with the smart dilution feature;
• continuous batch-wise injection of microsamples into the flame using a segmented flow star (SFS).
