ICP-OES is used for qualitative and quantitative determination of metals and certain non-metals in solution. The liquid sample is nebulised into a plasma where the temperature is sufficiently high to break chemical bonds, liberate elements present and transform them into a gaseous atomic state. A number of the atoms pass into the excited state and emit radiation. The frequency of this radiation is characteristic of the element that emitted it and as such can be used for identification purposes.
The intensity of the radiation is proportional to the concentration of that element within the solution and so can be used for quantitative purposes.
We have considerable expertise in sample preparationtechniques including:
Jobin Yvon ICP-OES spectrometer.
