Most inorganic solid materials are suitable for LA-ICP-MS, including:
Materials should be:
The Museum specialises mainly in the analysis of natural inorganic materials, together with some synthetic materials including glasses and ceramics.
Whilst analysis of the following materials is possible by LA-ICP-MS, they are not routinely analysed at the Museum:
Samples do not need to have surface preparation, but data quality is improved considerably if the samples are polished.
Any carbon coating from previous electron probe micro-analysis should be removed.
Any gold coating on samples previously imaged by scanning electron microscopy or ion probe analysis must be removed thoroughly. Residues of gold coating can severely affect LA-ICP-MS data quality.
Samples to be prepared (cut, mounted and polished) should be presented to the Preparation Laboratory at least 4 weeks prior to the LA-ICP-MS booking.
Odd sized and shaped samples may be accommodated. Please contact us for further information.
