ICP-OES (Inductively-Coupled Plasma Optical Emission Spectrometry) is an analytical technique for multiple elemental analysis. As a sample solution is purged through a flow of argon gas in the center of inductively coupled plasma with the excitation temperature up to 8000K. Each element atom will then emit its characteristic light at a specific wavelength. The spectrometer then records all light intensity with different element atom species. With the help of a series of calibration standards, the amount of the interested element can then be converted from the corresponding light intensity into the concentration reading. Theoretically, over 30 elements can be analyzed at the same time. A typical analysis time is less than a few minutes for 3 scans per sample.
