μX-Ray Diffraction (μXRD)
The Rigaku SmartLab is a multipurpose X-ray diffractometer system equipped with a high-flux 9kW rotating Cu anode and a 2D-detector. The X-Y-Z table holds samples up to 20 kg in weight and allows mappings on samples with a dimension of up to 87 x 100 mm. The device can be used for powder diffraction and for μ-spot analysis on different types of rock sections.
Samples: Rock powders, sections up to 20 kg and 87 x 100 mm
Spot size: 100 μm / 300 μm / 500 μm
μX-Ray Fluorescence (μXRF)
Bruker M4 Tornado is an energy-dispersive micro-X-Ray fluorescence spectrometer for the spatially resolved analysis of elements with atomic numbers from 11 (sodium). The device can analyze a wide range of samples such as large, inhomogeneous samples such or small particles. The M4 is equipped with capillary optics that realize spot sizes of 20 or 150 μm.
Samples: rock sections or crystals, max. 190 x 160 mm
Spot size: 20 μm / 150 μm
Laser Ablation Inductively Coupled Plasma Mass Spectrometry (LA-ICP-MS)
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
