Combined Matrix Effects in Plasma Pencil Spectroscopy
Original language description
Plasma pencil is a capacitively coupled jet discharge originally developed and used for surface modification of cultural heritage objects, wood, polymers, (nano)textile fibres and other modern materials. One of its modifications is currently tested as an alternative excitation source for optical emission spectroscopy with liquid model samples. It is a quartz tube (i.d. 2 mm, o.d. 4 mm) asymmetrical T-piece powered by 13.56 MHz at the typical forwarded power of 140 W. The working gas is argon flowing horizontally in the T-piece at 4 l min-1. The liquid sample is introduced vertically into the T-piece with a peristaltic pump, a concentric nebulizer and a Scott spray chamber.The carrier gas (Ar) flow rate is 0.3 l min-1. Previous studies showed good excitation capability especially on alkali metals, group two elements, copper and zinc [1]. Now a study of matrix effects of easily ionizable elements (EIE) in mixtures is presented.
