Automatic soil sample preparation

As the analysis results should be truly representative for the area being tested, large volumes of soil samples need to be consistently prepared and tested. Soil cannot be introduced to analytical instruments directly. To release the substances that need to be analyzed, a specific sample preparation procedure is performed. This procedure can include sieving, adding chemicals and shaking for example. Automating this preparation procedure improves the consistency and reliability of the laboratories’ services. In addition, it reduces the use of consumables significantly.

Automatic soil sample preparation

The results of soil analysis are used for a wide variety of purposes. In the agricultural sector, it provides valuable information to optimize crop production and to save costs by applying only the amount of fertilizer needed. In the environmental sector, soil testing also plays an important role. The data offers a basis for research and advice or to protect the environment from contamination, for example.

Soil sample preparation procedure

Soil presents a series of challenges in terms of the homogenization and pretreatment of the sample, all of which can impact the final analytical results significantly. As soil samples are solid, they cannot be introduced into the analyzer directly. Acid digestion or extraction are examples of a soil sample preparation procedure.

Typical soil preparation steps

The following sample preparation steps are common when preparing and analyzing soil samples:

  • Sampling
  • Sieving
  • Shaking
  • Pipetting
  • Cleaning
  • Filtering
  • Adding chemicals
  • Capping and de-capping
  • Transporting to the analyzer
