Petrographic analysis

Sample preparation

Petrolab are experts in materials preparation producing petrographic thin sections from samples and specimens of

  • rock
  • aggregate
  • concrete and other similar materials

We operate the first Pelcon Automatic Thin Section Machine in the UK, which produces high quality thin sections.

Our research has allowed us to push the boundaries of sample preparation to implement new resin technologies and unique powder preparation techniques for polished blocks including:

  • representative sample selection
  • ability to prepare low sample masses
  • successful preparation of coal, graphite and fuel ash for automated mineralogy
  • de-agglomeration techniques
  • cutting edge impregnation to combat density settling
