Precise analysis of calcium stable isotope variations in ...
Laser ablation (LA) is potentially an interesting technique to measure natural variations (δ 44/42 Ca) of calcium isotopes in calciumrich minerals because it allows spatial resolution and avoids microsampling and consecutive wet chemistry. We developed a matrixmatch sample/standard normalization method and used an Excite 193 nm Photon Machines LA system coupled to a Neptune plus MCICPMS ...
