Energy assistance in laser induced plasma spectrometry (LIPS) by a synchronized microsecond-pulsed glow discharge secondary excitation
Abstract
The design and preliminary experimental results are presented of a new LIPS chamber permitting the creation of a sub-sputtering threshold glow discharge (GD) environment that is pulsed synchronously with an ablation laser. The new dual GD-LIPS synchronous scheme provides significant signal enhancements (up to 75×) when compared to
