In laser ablation analysis the choice of which inductively coupled plasma mass spectrometer (ICP-MS) type to use is dependent on the application. Chronometers requiring epsilon level precision are measured on multi-collector ICP-MS; determination of the trace elemental composition of a material is more appropriate on Quadrupole based instruments.
High resolution elemental mapping of biological samples by high sensitivity, fast-scanning LA-ICP-Q-MS

Elemental mapping in cells and tissues is an important technique for improving our understanding of the role of metals in various biological processes as well as in emerging diagnostic techniques. Through instrumental advances in laser sampling (for example fast washout laser sample cells) and the increased scan speed, sensitivity and specificity of modern ICP-MS instruments, the scale of the spatial measurement of metals is ever decreasing. In this poster, the LA-ICP-MS workflow for spatial elemental analysis in a range of biological samples will be described.
