ICP-AES is a measurement technique that ARkival uses to determine elemental concentrations in materials from minute trace amounts to major compositions. Statistical concentration data results can be obtained for about 70 elements with detection limits in the parts per billion range.
ICP-MS is a type of mass spectrometry that ARkival uses for detecting metals and several non-metals at concentrations as low as one part in 1015 (part per quadrillion, ppq). It is used in tissue containment analysis involving exceptionally small diagnostic and treatment material quantities and types.
