Schematic layout of different components:

A schematic layout of an ICP-AES spectrometer is given in Figure. The sample in the solution form is nebulised and injected into the plasma source with the help of a suitable nebuliser. The emitted radiation is passed by monochromator and after dispersion it is detected by a photodetector and sent to the processing unit for the processing and generating suitable output.

You have learnt about the creation and features of various kinds of plasma source in the previous section.  While we are discussing about the instrumentation for ICP-AES, the inductively coupled plasma acts as a source.
