ICP, which stands for “Inductively Coupled Plasma,” is a special testing method that allows us to find out what chemical components different samples are made of. To use ICP, we need a device called a plasma generator. It generates a very hot gas called plasma. This plasma can reach temperatures as high as 10,000 degrees Celsius. When the sample is ready for analysis, we introduce it into the plasma. We can do this in the form of fine droplets or aerosol, for example. When the sample is in the plasma, the chemical components in it begin to react with the hot plasma ions. As a result of these reactions, the chemical components emit characteristic electromagnetic radiation. This radiation is collected by a special device, which we call a spectrometer. The spectrometer allows us to identify which chemical components are present in the sample and in what quantities.
