Powder x-ray diffraction
Building Chemistry, Building Biology, Hygiene
| Measurement | Qualitative phase analysis, quantitative phase analysis by Rietveld method, determination of amorphous phase by internal or external standards |
| Measurement object | Powdered samples or little solid samples: minerals, rocks, cements, slag, ceramics, mineral building materials, concrete, mortars |
Technical data
| Diffractometer | D2 phaser |
| X-ray tube | Cu-radiation (30 kV, 10 mA), Ni filter |
| Goniometer radius | 141.1 mm |
| Detector | LynxEye (1D detector) |
| Measurement range | +5 to +140° 2Theta |
Special features
| LynxEye detector | The one-dimensional detector allows fast measurements with high accuracy. |
| External standard | The application of an external standard allows the determination of the amorphous phase without contamination of the sample. |
More information
For the preparation of the samples a micronizing mill (McCrone mill) is used.
