Surfatron microwave-induced plasma

A surfatron microwave-induced plasma was reported for the selective detection of catechols after SFC separation of the compounds as cylic bo-ronate esters [39]. An available spectroscopic system was modified to utilize... 

Plasma sources are capable of producing intense emission from the elements. Types of plasma used in chromatographic detection are microwave induced plasmas (MIP) and inductively coupled plasma (ICP). An argon plasma is sustained in a microwave cavity which focuses into a capillary discharge cell. The most widely used cavities are cyhndrical resonance cavities and surfatron that operates by surface microwave propagation along a plasma column. Atmospheric pressure cavities are very simple to interface with capillary GC columns.
