Analytical and technical aspects of free discharge end of plasma pencil
Original language description
Plasma pencil has been employed as an alternative excitation source for atomic emission spectroscopy determination of elemental contents in solutions [1, 2]. The new arrangement of the discharge tube enables to measure spectra from the free discharge end without shielding by the quartz wall. Most intensive atomic spectra can be recorded as close as possible to the ground electrode but it is also possible to record the plasma tip radiation in the range of about 0-10 mm from the ground electrode or as long as the discharge tip is formed behind the ground electrode. The pencil sustainability and stability were tested under various operating conditions. Carrier gas and plasma gas flow rates as well as forwarded power were changed and spectra of selected elements were recorded in order to yield best signal to backgroud ratio and discharge stability.
