About us

The laboratory consists of three parts: an X-Ray analytical, a micro-analytical and an inorganic chemical unit. The available analytical facilities enable us to analyse the phase and chemical composition of solid materials both at the macroscopic and microscopic scale. The major profile of the laboratory is the analysis of geological materials; however, significant experiences are possessed on the analysis of (industrial) ceramics, metals, glasses, and materials of the cultural heritage. Basic and special sample preparation fecilities are also available there.

Special areas of the analyses are as follows:

- clay mineral identification and mineral structure analysis primarily related to the study of physicochemical and sorption properties of clay minerals,

integrated archeometric analysis related to research on archeology, history of art, restauration, and protection of monuments,

- integrated phase and chemical micro-analyses down to the several tens of micrometer scale,

-  planning and performing sorption experiments, quantifying the sorption capcity of soils, sediments and rocks.

 


Infrastructure


Rigaku DMax RapidII X-Ray diffractometer


The instrument is equipped with a Cu anode micro-focus tube and 2D image plate detector system. Collimators between 20 and 800 micrometers enable us to carry out point phase analysis on prepared solid surfaces.

Rigaku Miniflex 600 X-Ray diffractometer


This benchtop instrument is equipped with a 600 W Cu anode tube and a graphite monochromator and used for routine phase composition analysis of powder samples.

Philips PW1729 X-Ray diffractometer



This instrument is equipped with a 2.2 kW Cu anode tube and graphite monochromator and used for routine phase composition analysis of powder samples.

Philips PW2404 X-Ray fluorescent spectrometer


This wavwlength dispersive instrument is equipped with a 4 kW Rh anode tube and 6 analyzing crystals (LiF220, LiF200, GE111, PE002, PX1, PX4) to detect and quantify chemical elements between Na and U fown to a few mg/kg concentrations in solid samples prepared as pressed powder pellets or fused beads.

Spectro XSort Combi
handheld X-Ray fluorescent spectrometer


This energy dispersive instrument is equipped with a 250 W Rh anode tube to detect and quantify elements between Mg and U in two calibration methods (environment and alloys) in solid samples without any special sample preparation out of the laboratory.

Jeol Superprobe JCXA733
electron microprobe


Micro-texture and fabric, point chemical micro-analysis (of elements between F and U) and elemental mapping of solid materials can be carried out down to a few micrometers of resolution in samples of low water and organic matter content and resistant to high vacuum.

Perkin-Elmer AAnalyst 300 atomic absorption spectrophotometer


The instrument can be equipped with a graphite furnace and used for high precision trace element analysis from solution (Na, Mg, Al, Si, K, Ca, Ti, V, Cr, Mn, Fe, Co, Ni, Cu, Zn, As, Se, Rb, Sr, Y, Zr, Nb, Mo, Cd, Ba, Pb).

DKK TOA AUT701 automatic tirtrator



Parallel automatic titrator to study the point of zero charge and acid/base buffering capacity of soils and sediments, as well as to carry out pH-stat experiments.
