Atmospheric-pressure plasma

The plasma state of matter is defined as a gas wherein a certain portion of particles are ionized. Plasmas can be classified by temperature in thermal and non-thermal plasmas (often referred to as “cold plasmas”). The latter are characterized by a significant disparity of the electron and the ion temperature. Non-thermal plasmas are i.e. used for surface modification, cleaning or coating. We construct non-thermal plasma sources for applications in analytical chemistry.
