High resolution ICP-MS (HR-ICP-MS) is widely used in
geochemical applications for interference-free multielemental
determinations in complex sample matrices and
for the measurement of precise isotope and elemental
ratios at low concentrations, as well as a detector for laser
ablation analysis. The linear dynamic detection range is of
immense importance in ICP-MS because of the wide range
of elements and concentrations to be analyzed in a single
analysis. This is particularly critical for laser ablation
analyses where, in addition to measuring ultra-trace
elements, a major matrix component is often used as an
internal standard to correct for the amount of material
ablated from each sampling point.
