Crystal Structure Model Development For Soil Clay Minerals – I. Dietel, J., Gröger-Trampe J., Bertmer M., Kaufhold, S., Ufer, K., Dohrmann, R.is used for the diagnosis of the clay minerals present. XRD analysis of air dried and ethylene glycol solvated specimens is performed, and dependent on the analytical requirements also XRD analysis after potassium saturation, stepwise heating, etc. After suitable disaggregation and dispersion the colloidal material is collected stepwise, homogenized and prepared on flat ceramic discs. In addition to the bulk rock analysis XRD of clays requires separation of clay fractions.

The second MPD Pro uses Co radiation and contains a „scientific X’Cellerator“ as second detector (special clay mineral analysis, Figure 1 in the middle), and the third MPD Pro uses Cu radiation and contains a PIXcel detector as second detector (climate chamber CHC plus +, Anton Paar, 95% RH from 10 to 60 ☌, Figure 1 on the right).įigure 2: Typical evaluation of the qualitative mineral composition Source: BGR One MPD Pro uses Cu radiation and contains a „scientific X’Cellerator“ as second detector (rock analysis, sample changer, Figure 1 on the left). Each double detector unit contains a proportional counter which is equipped with a focused monochromator. All three PANalytical machines are equipped with double detector systems the type of detector for a given analysis can be chosen using software only. Mineral analysis of rocks and soils is performed with three PANalytical MPD Pro XRD machines (Figure 1) and one Seifert XRD 3003 TT (Figure 2).
