Optical emission spectrometer with inductively coupled plasma, AGILENT 5900 ICP-OE
Inductively coupled plasma optical emission spectroscopy (ICP-OES) is an analytical technique used for the detection of various chemical elements. It is a type of emission spectroscopy that uses an inductively coupled plasma to produce excited atoms and ions that emit electromagnetic radiation at wavelengths characteristic of a particular element. A plasma is a high-temperature source of ionized gas (usually argon) maintained at high frequencies (MHz) by inductively coupled electric coils. The temperature of the plasma is in the range of 6000 to 10000 K. The intensity of emission of light of different wavelengths is proportional to the concentrations of elements in the sample.
Due to the wide linear range, good selectivity, low chemical interference and fast analytical performance, this is a suitable system for simultaneous multi-element analysis. ICP-OES is used for samples with high concentrations of dissolved solids or with suspended particles and is therefore the most suitable system for the analysis of samples of complex aqueous matrices or concentrated solutions. Compared to the ICP-MS system, maintenance is easier, the instrument is less sensitive, and it is also more robust in use. In addition, compared to analysis with the ICP-MS system, with ICP-OES it is possible to determine more accurately the concentrations of elements of the first and second groups of the periodic table (e.g. Na, K, Mg, Ca), which is important for the characterization of construction and recycling materials.
Rental of equipment and access to it together with a qualified operator is possible by prior arrangement. The price of the investigation depends on the complexity of the experiment.
The equipment was purchased under the ARRS public tender for co-funding of scientific research equipment package 20.
