ICP-MS is used for low level measurement of elements in samples – minerals, trace elements, and heavy metals being of most common interest. Samples are atomised in a very hot plasma flame, and detected/quantified in an associated mass spectrometer.
PerkinElmer nexION 300D ICP-MS
A modern ICP-MS, validated for over 40 elements in a range of sample types - water, organic, and inorganic. Also has potential for rare earth elemental analysis for authenticity testing, and nanoparticle analysis.
