Samples that can be analyzed
- bulk
- films
- powders
Please note: sulfides, iodides and fluorides, especially in the form of powders, are excluded because they may pollute the analysis chamber.
You are requested to keep the samples you bring for analysis clean. The surfaces must not come into contact with the skin or the walls of the boxes in which the samples are stored.
