“…The elements Zn, Cd, Sn, Sb, Au, Pb, and Bi were measured, and their contents were used to distinguish forgery in silver antiques. Similar studies were reported by Wanner et al 113 for trace element analyses of archaeological samples such as ancient coins, various antique silver items, and ancient iron. Owing to surface roughness of the samples, an autofocus system was used to achieve reproducible ablation conditions.…”

Laser ablation (LA) is a unique technique to transform a solid sample into vapor‐phase constituents, which then can be chemically analyzed by atomic spectroscopy. Ablation brings many exciting capabilities to the field of chemical analysis, primarily because of the laser‐beam properties. The ability to analyze directly any solid samplewithout sample preparation and minimal sample‐quantity requirements are just some of the unique capabilities. This article discusses current issues related to using LA in atomic spectroscopy. A general introduction to LA sampling is presented along with a comparison with other solid sampling techniques. The critical issues for all analytical techniques are calibration, accuracy, and sensitivity. Techniques that have been demonstrated to address these analytical characteristics and define these parameters for LA are investigated in detail. Finally, many unique applications are described, ranging from dating geological materials to providing crime‐scene evidence. Most of these applications could not be performed without the use of a laser beam. The inductively coupled plasma (ICP) will be emphasized in this article because it is currently the most prevalent excitation and ionization source for chemical analysis using LA.

“…Further instrumental modifications were carried out in the first applications of LA-ICP-MS on antiques metal objects in order to minimize the spot diameter on the sample surface, and thus making the technique virtually non-destructive but still maintaining high sensitivity and reproducibility, The autofocus system developed by Wanner et al [42] allowed to easily correct the focusing procedure in case of the use of several laser wavelengths as well. In the case of silver antiques studied by Devos et al [40] craters caused by ablation were small enough to be almost invisible to the naked eye.…”

“…In addition to to the aforementioned general advantages of solid sampling, LA also offers a lateral resolution down to ~5 µm and a depth resolution down to <1 µm [1,2,3,4,5,6]. However, with LA, accurate quantification is not an easy task, especially if no reference material showing a matrix composition similar to the samples to be analysed is available.…”

Electrothermal vaporisation ICP-mass spectrometry (ETV-ICP-MS) for the determination and speciation of trace elements in solid samples – A review of real-life applications from the author's lab

The use of electrothermal vaporisation (ETV) from a graphite furnace as a means of sample introduction in inductively coupled plasma mass spectrometry (ICP-MS) permits the direct analysis of solid samples. A multi-step furnace temperature programme is used to separate the vaporisation of the target element(s) and of the matrix components from one another. Sometimes, a chemical modifier is used to enable a higher thermal pre-treatment temperature, by avoiding premature analyte losses (stabilisation) or promoting the selective volatilisation of matrix components. In almost all instances, accurate results can be obtained via external calibration or single standard addition using an aqueous standard solution. Absolute limits of detection are typically ~1 pg, which corresponds to 1 ng/g for a typical sample mass of 1 mg. Real-life applications carried out in the author's lab are used to illustrate the utility of this approach. These applications aim at trace element determination in industrial and environmental materials. The industrial materials analysed include different types of plastics - Carilon, polyethylene, poly(ethyleneterephtalate) and polyamide - and photo- and thermographic materials. As samples from environmental origin, plant material, animal tissue and sediments were investigated. Some applications aimed at a multi-element determination, while in other, the content of a single, but often challenging, element (e.g., Si or S) had to be measured. ETV-ICP-MS was also used in elemental speciation studies. Separation of Se-containing proteins was accomplished using polyacrylamide gel electrophoresis (PAGE). Subsequent quantification of the Se content in the protein spots was carried out using ETV-ICP-MS. As the volatilisation of methylmercury and inorganic mercury could be separated from one another with respect to time, no chromatographic or electrophoretic separation procedure was required, but ETV-ICP-MS as such sufficed for Hg speciation in fish tissue.
