MfN - Museum für NaturkundeThe Electron Microprobe Lab houses a JEOL JXA-8500F electron microprobe that is equipped with a field-emission cathode, five wavelength-dispersive X-Ray spectrometers, and an energy-dispersive spectrometer. Electron microprobe analysis (EMPA) is mainly used to quantitatively investigate the chemical composition of rocks and mineral phases in the micrometer to centimeter range.
Typically, polished sections of rocks or minerals are used for this purpose, but highly vacuum-resistant fossil …
MfN - Museum für NaturkundeThe Micro X-Ray Fluorescence (µXRF) Lab houses two spectrometers used for element dirstribution maps and quantitative analysis of the main and trace elements. The Bruker Tornado M4 plus can analyse samples up to 16x20 cm and runs under vacuum to allow detection of low mass elements. The lowest spot size is 20 µm. The Bruker Jetstream M6 can analyse large samples with a maximum mapping size of 60x80 cm. It usually runs under atmosphere (no detection of low mass elements). The spot size is …
MfN - Museum für NaturkundeMineralogical preparation covers the spectrum of coarse and fine sawing work, polished sections and thin sections polished on one or both sides. Surface and thin sections can be produced in Giessen format or as one-inch cylindrical sections. The laboratory is equipped with various rock saws, an inner diameter saw, two GNM grinding machines, two Logitech polishing machines, and a polishing machine for vibration polishing.
MfN - Museum für NaturkundeThe Raman Spectroscopy Lab is equipped with a Horiba LabRAM-HR laser Raman spectrometer that is used to identify and structurally characterize mineral phases, glasses, and organic substances. It is suitable for almost all areas of object-oriented research. Raman spectroscopy provides non-destructive information on the molecular or crystalline structure of samples down to the micrometer range. The Raman spectrometer is equipped with three lasers of different wavelength (an air-cooled …
MfN - Museum für NaturkundeThe Scanning Electron Microscopy Lab houses a JEOL JSM-6610LV scanning electron microscope (SEM). The SEM is equipped with a LaB₆ cathode and is coupled to a Bruker Quantax 800 energy-dispersive X-Ray spectrometer, a cathodoluminescence detector, and an electron-backscatter diffraction detector. The SEM is typically used for structural and chemical analysis of rocks, minerals, and fossils. The large sample chamber holds objects up to ten centimeters in size. The SEM can be operated in a …
MfN - Museum für NaturkundeThe Scanning Electron Microscopy Lab additionally houses a Lumic HC3-LM "hot-cathode" cathodoluminescence (CL) microscope that is coupled to an optical microscope fitted with a color CCD camera. Color CL signals can be obtained from thin-sectioned rock and mineral samples, and CL signals, recorded with the CCD camera, allow, e.g., identification and spatial mapping of zoning patterns in minerals such as zircon and calcite.
MfN - Museum für NaturkundeThe X-Ray Fluorescence (XRF) Lab houses a Bruker S8 Tiger X-Ray fluorescence sequence spectrometer that is used for quantitative analysis of the main and trace elements of bulk rock and mineral samples. Element contents as low as the parts per million (mg/g) range can be obtained by XRF from bulk samples that were previously either finely ground and pressed into a tablet or molten and subsequently cast into a glassy disk. The analyser can be used on-site as well as for sample-based research …
