Laser Ablation Inductively Coupled Plasma Mass Spectrometry Laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS) has evolved into a well-established technique for both fast qualitative and quantitative elemental mapping, characterized by high lateral resolution (micrometers) and high sensitivity. A pulsed laser (e.g., ns or fs) is employed at a certain repetition rate (typically > 10 Hz), with the sample-mounted stage moving beneath the laser beam, operating in a laser raster mode. The laser-induced aerosol is transported from a sealed ablation chamber to the ICP-MS using a continuous flow of inert gas, such as helium. Wash-out times for conventional low-dispersion laser-ablation…

Laser-Induced Breakdown Spectroscopy One of the plasma generation procedures handled by the research group is the use of high-intensity pulsed lasers. The LIBS technique, acronym for Laser-Induced Breakdown Spectroscopy, is based on the analysis of laser-generated plasmas and its origin dates back to the decade of the 1960s, in parallel with the appearance of the first lasers. LIBS is used for the detection and quantification of chemical elements in all types of samples, regardless of their state of aggregation, since its application is common either on solid, liquid and gaseous samples. LIBS represents a versatile technique that implies a low-cost…

Solution Cathode Glow Discharge Optical Emission Spectroscopy Glow Discharges operating at atmospheric pressure have shown a strong analytical potential for the fast analysis of liquids. In particular, the electrolyte-cathode atmospheric glow discharge (ELCAD) or Solution Cathode Glow Discharge (SCGD) is an alternative source for a fast elemental analysis of liquids. In essence, ELCAD, introduced by Cserfalvi et al.[1] in 1993, is a conically shaped GD microplasma with 3-4 mm base diameter and 3 mm height, operating between an electrolytic solution cathode and a metal (tungsten) rod anode under ~1 kV plasma voltage and 70 mA discharge current (see Figure 1)….

Pulsed Glow Discharge Time-of-Flight Mass Spectrometry GELP has a long experience in the field of low-pressure glow discharges (GD) coupled to both Optical Emission Spectroscopy (OES) and Mass Spectrometry (MS). The lines of research the group has taken part in include instrumental developments, fundamental studies about the plasma processes and the development of analytical applications. In the last years, the research activity of GELP in low-pressure GD has been focused on the study and optimization of a Radiofrequency Glow Discharge Time-of-Flight Mass Spectrometry (RF-GD-TOFMS) prototype, which was developed in the frame of the European project New Elemental and Molecular Materials…
