Data processing

Data processing

Our Laser ablation system is optimised for semi-automated operation to maximise sample/cost efficiency. Routine analysis of foraminiferal geochemistry, for example, runs at 50-100 measurements per hour. These large numbers of measurements require special ways to process laser ablation data. We use Glitter and Iolite software packages to speed up data processing.  We developed several data regression protocols for Iolite package specifically for trace metal analyses and Mg isotopes measurements.
