A special foil needs to be put on the core surface to avoid contamination. Please place the foil carefully and as accurate as possible on the sediment surface. Please also avoid (or at least to minimize) wrinkles or air bubbles. Tools like a roll or a lab tissue work best in helping to flatten the foil.
Placing the section in the scanner

Please measure and write down:
- the length of the core section,
- also note any additional potential measurement postions ("add")
- or measurement positions you need to avoid ("skip") like cracks and holes in the core surface.
The core section needs to be placed horizontally into the holders of the scanner. A level helps to improve the adjustment.
