Bruker D8 ADVANCE diffractometer


The X-Ray Diffraction Laboratory of the IGS PAS performs widely implied analyses, mainly in terms of mainly powder X-Ray diffraction. We have, i.a., a D8 ADVANCE diffractometer of Bruker, equipped with superfast VÅNTEC-1 detector. It is an ultra-precise linear position-sensitive detector (LPSD), of much higher capabilities than traditional scintillation detectors. Using of this LPS detector leads to high reflection-to-background intensivity ratio. An additional factor deciding of high quality of the data is the use of radial soller. By the 1-second-per-step counting time (in terms of scintillation counter) we obtain much better diffraction profile, theoretically 400 times better than expected for traditional zero-dimensional detection.

Routine and capillary-mounted tiny sample powder XRD analyses are performer on two-stage CGR/INEL/Rigaku apparatus. Thermal analyses are conducted with the use of Q-1500D derivatograph of Paulik-Paulik-Erdey.

Analytical capabilities

  1. Standard qualitative analyses, i.e., phase analyses, for virtually any sample aliquots, also for complex crystalline and crystalline/amorphous mixtures (various geological, chemical and industrial samples, smelter ashes, ceramic materials, magnetic separates, etc.).

  2. Full quantitative analyses with the use of Rietveld method (TOPAS software, v. 4.0), with structural analysis (unit cell parameters, crystallite size, strain of particular components; crystallinity degree / amorphous phase content of the sample).

  3. Grazing incidence diffraction – sample surface analysis

  4. Transmission geometry analysis (e.g., for polytype analysis)

  5. Thermal experiments in the mri Radiation chamber (analysis of phase transitions with real-time diffraction)

    Thermal experiment involve deposition of a tiny aliquot of sample powder in form of a suspension (ethanol, water, acetone, etc.). It is possible to plan the particular stages of the process with varying heating and illumination conditions. For the whole of below cases it is possible for introducing a delay before starting the illumination, after reaching the demanded temperature.

    Orders for thermal experiments are accepted all year long. However, due to the need of assuring the permanence of the laboratory work and time-consuming reconfiguration of the apparatus, experiment are to be performed between November and January. Exceptions are possible when needed, e.g., in case of at least 10 sample set, after agreement.

  6. Isogranular grinding of samples to in the McCrone mill with ZrO2 pellets – useful for obtaining best quantitative results especially in case of clayey samples.

  7. McCrone isogranular mill

  8. Heating of samples in the programmable Nabertherm oven.

    Specification: maximum temperature of ca. 1160 °C, programmable rate of temperature increase/fall, programmable preservance time in demanded thermal conditions.

  9. Nabertherm oven
