Abstract
A glow discharge mass spectrometry device and method, the device including a glow discharge lamp (), gas flow-injection elements, the glow discharge lamp being suitable for forming an ablation plasma in the presence of a plasma gas, and a mass spectrometer. The device further includes heating elements () suitable for heating a gas flow () upstream of a cell (), the gas flow-injection elements being suitable for injecting into the glow discharge cell a gas flow () heated to a temperature T for a duration D, and pumping elements () being designed to pump a flow of gaseous species () out of the cell for the duration D, so as to decontaminate the surface of the sample () and/or the inner walls of the glow discharge cell () before an ablation plasma () is ignited.
