| Description | Plasma pencil is a kind of a barrier discharge operated in a quartz tube at various conditions, like various gases or gas mixtures, pressure, alternating or direct current, continuous or pulsed regime etc. It is a simple and effective tool used for surface modification of wood parquets, underliquid deposition of zinc on the glass plate and cleaning of metal objects in the continual regime, plasmacancer cell interactions, tooth root canal disinfection, inactivation of a gram-positive Staphylococcus aureus bacteria and portable molecular emission detector in the pulsed regime and as a low-purchase excitation source in the plasma pencil analytical spectroscopy in both regimes and for many other applications. A plasma pencil operated in the two-electrode connection in the both regimes separately at laboratory pressure, boosted/ powered by a symmetrical sinus current with radio frequency 13.56 MHz and flowed with high purity argon was used for realization of measurements of analytical element signal dependences on the duty cycle and on the modulation frequency. |
