LA-ICP-MS is a micro-destructive technique which enables the in situ analysis of elements and isotope ratios across the periodic table at very high scanning speeds and with very low detection limits. The 8900 ICP-QQQ is able to utilize reactive cell gases to resolve difficult spectral interferences. Samples: rock sections (max. 10 x 10 cm), 1 and 1/2 inch rounds; Spot size: 1 - 155 μm
