Spectrochimica Acta Part B: Atomic Spectroscopy, 2000
Infrared laser ablation was studied for application to the analysis of plasma-sprayed tungsten carbide/cobalt coatings. The potential of the laser induced argon-spark (LINA-Spark), as a sample introduction device in inductively coupled plasma atomic emission spectrometry was studied.

Abstract Irradiation of silica with a frequency quadrupled Q-switched Nd-YAG laser pulse produces Sim± and SimOn± ions of mass up to about 600 amu. The experimental molecular ion distributions in LAMMA are similar to those observed in SIMS and SSMS, although data are only available for m values up to 5 and 3, respectively.

The potential of the laser-induced argon spark atomizer (LINA-Spark atomizer) coupled with ICP-AES as a convenient device for direct analysis of WC/Co powdered precursors of sintered hardmetals was studied. The samples were presented for the ablation as pressed pellets prepared by mixing with powdered silver binder containing GeO2 as internal standard.

A laser spark spectrometry study was carried out on the effect of the silver content in cotton fabric on the extent and duration of the antiseptic effect. Durable antiseptic properties of various strength were found to appear only after tannide fixation of the composition in the fabric structure.

Analysis of Solids by Spark Source and Laser Mass Spectrometry
1983In about 1960 two scientific developments occurred which have a direct bearing on this topic. One was the demonstration of the first laser (1) whose impact on this topic will be discussed later. The other was the scientific development in the late 50’s and the commercial availability in the early 60’s of the spark source mass spectrometer (SSMS ...

Fresenius Zeitschrift f�r Analytische Chemie, 1988
After describing the design and properties of the ion sources, the analytical performances of spark source, laser, glow discharge and secondary ion mass spectrometry are compared. The criteria are the sample requirements, the detectable elements, the detection limits, element sensitivity factors and the achievable accuracy.
