The potential of laser ablation-single collector-inductively coupled plasma-mass spectrometry for discrimination among Spanish antique lead-glazed ceramics according to age and workshop has been investigated. In order to obtain the required precision, pressurizing the dynamic reaction cell (DRC)...
Aerosol transport efficiency in UV-ns LA-ICP-MS of less than 100% requires a representative aerosol composition for precise and accurate quantitative analysis. Therefore, aerosol expansion related changes in the composition of aerosols generated using a 193 nm excimer laser were studied within...
The application of a high-throughput introduction system to the analysis of natural and certified water samples is described. The introduction system consists of an autosampler, a switching valve, a high efficiency PFA-ST nebulizer and Peltier-cooled cyclonic spray chamber to perform analysis by...
Internal standards are routinely used with inductively coupled plasma mass spectrometry (ICPMS) to minimize the impact of signal instability. Previous studies indicate that internal standard choice should be directed by similarities in mass, but they neglect to address the possibilities of...
It is now well known that traces of molecular gases such as hydrogen or nitrogen can affect significantly the electrical characteristics, sputtering rates and relative intensities of emission lines in glow discharge optical emission spectrometry (GD-OES). These changes, caused by the molecular...
A low-flow low-power annular-shaped microwave induced helium plasma operating at atmospheric pressure has been developed for use in optical emission as well as mass spectrometry. The first study on the plasma formation and fundamental investigation of the plasma generated at helium flow rate...
