Sample Preparation

Every step, from sample receipt until the laboratory begins the analysis must be suitable for the specific needs of your project and sample matrix and completed with meticulous care to minimise contamination. Our expertise and state-of-the-art equipment ensures your sample preparation will provide results you can trust.

Our team can also provide advice on the most suitable sample preparation methods to meet your needs and will work closely with you to understand exactly what answers you want and how best to get them.

Our sample preparation services cover from rock chip, drill core, stream sediments, to soils and vegetation .

Rocks and drill core

Rocks and drill core samples are crushed to 70% passing 2mm, then a representative split is taken and pulverized to 85% passing 75μm.

Soil and sediment

Soil and sediment samples are dried and then screened to the desired mesh size. The undersized (-) fraction is analyzed and the oversized (+) fraction is discarded unless otherwise specified.

Vegetation

Depending on requirements, vegetation samples are either dried and macerated to 1mm, OR, dried then ashed at 475°C, prior to analysis.

Other

We include the following sample preparation methods, together with a range of
miscellaneous options:

  • Core sawing
  • Composite preparation
  • Specific gravity
