Attività

This laboratory is designed to prepare samples both for X-ray powder diffraction and other analytical techniques requiring specimens as fine powders. It is advisable using the lab only for small-volume (max. 20 mL) solid samples.

Separating the clay-size fraction from coarser particles and ethylene glycol treatment to expand swelling clays are also feasible in this lab.

Strumentazione

- agate mortars and pestles (hand grinding)

- McCrone ® Micronizing mill with zirconia grinding elements indicated for obtaining grain sizes < 5 micron

- analytical balance (max 220 g, precision 0.1 mg)

- internal standards for quantitative phase analyses (zincite, corundum)

- specimen holders for Panalytical diffractometers operating in Bragg-Brentano geometry: 27 mm and 17 mm cavity diameter, Si zero-background holders, holders for bulk samples

- boron glass capillaries for X-ray diffraction measurements in transmission geometry.
