Development of a Laser Ablation-Hollow Cathode Glow Discharge Emission Source and the Application to the Analysis of Steel Samples

Abstract

The glow discharge has a long history of application in the field of analytical chemistry, 1 and has been found to be a potential spectroscopic source for atomic emission [2][3][4]

A laser ablation millisecond-pulsed glow discharge time-of flight mass spectrometer (LA-GD-TOFMS) for quasi-simultaneous elemental and molecular analysis

“…11,27 Over the last few years, several groups have also examined the possibility of analyzing solids using laser ablation (LA) based GD-setups in combination with atomic emission detection. 28,29,30,31,32,33 Here, the GD acts as a secondary excitation or ionization source for the ablated material permitting to analyze both conducting and insulating materials which, otherwise, can only be accomplished by rf GDs or by preparation of a conductive pellet. Recently, Shelley et al have reported on a LA system coupled to a flowing atmospheric pressure afterglow.…”

Inorganic mass spectrometry as a tool for characterisation at the nanoscale

“…Furthermore, the sampling and ionisation steps are spatially and temporally separated and, thus, can be independently optimised. At present, such a combination is almost unexplored [64][65][66]. Tarik et al [66] have recently investigated the analytical capabilities of LA coupled with pulsed GD-TOFMS.…”

Analytical potential of a laser ablation–glow discharge–optical emission spectrometry system for the analysis of conducting and insulating materials

“…In combination to optical emission spectroscopy (OES) several studies have demonstrated the capabilities of the GD to excite the ablated material. Naeem et al proposed a LA-hollow cathode GD in helium atmosphere for the determination of minor elements (Cr, Mn and Ni) in low-alloyed steel samples using Fe as internal standard [13]. Some papers have also been published reporting the use of argon pulsed-GD.…”
