The measuring methods vary from mechanical, inertia-based separators (e.g. impactors and cyclones) to methods exploiting optical and electrical interactions. In the following, the most commonly used of these are discussed.

When returning to the normal lower energy level, excited molecules give up their extra energy, giving rise to another radiation called fluorescent radiation (also in the ultraviolet wavelength range), the intensity of which is detected.
