Information for users

If you have any information concerning the analysis of your materials, please contact us. We would be more than happy to respond and give advise to your needs.

Reservation of terms

Ordering of terms of analytical works is possible after an agreement with the laboratory staff, Phone: +420 251 085 220, 219; e-mail: ondrej.pour@geology.cz , patricie.halodova@geology.cz

Terms will be reserved regarding the date of the order of analytical works and an actual distribution of capacities approved by the Director of the Czech Geological Service. The laboratory staff will be pleased to consult details of your requirements when ordering terms. It is recommended to order terms of analytical works at least 14 days before the planned term of analytical works.

In a case the instrument will be, from any reason, out of order, you will be without delay informed about the term change. As far as you will wish to cancel your fixed term, please notify it by phone or e-mail at least 2 days before.

Requirement on analyzed samples

Samples for quantitative microanalysis have to be perfectly polished. Quality of the sample surface is controlled by an optical microscope in the reflected light. In a case of embossed and unsatisfactory polished sample surfaces it is possible to carry out a qualitative analysis only.

In case of analysis of non-conducting sample we provide carbon coating. There is necessary the samples for carbon coating to deliver the samples in advance, cca 3 days before the ordered term.

There is possible, after a preliminary agreement, for scanning of sample surface in secondary electrons a sputtering by other suitable materials (Au, Au-Pd, Cr). In these cases it is necessary to hand over the samples to the laboratory staff at least 3 days before the agreed term.

For the EBSD analysis it is necessary to adjust the sample surface by the method of chemical polishing. In such a case it is necessary to deliver the preparates (thin sections, polished sections) to the laboratory staff at latest 5 working days before agreed term of analysis. High quality polished samples only will be accepted.

Sample dimensions:

  1. standard polished thin section on underlying glass of dimensions 48 x 28 x 2 mm
  2. polished section of diameter 25 mm, height max. 20 mm

In a case of other dimensions and farther special requirements on samples contact, please the laboratory staff.
