Why samples are representative
A sample is deemed representative depending on the preparation methods and obtained features. Only a properly prepared sample with specific features is considered reliable and can, therefore, help identifying the material’s value.
- First of all, the material is blended. We own mixers of different sizes and choose which one to use depending on the total quantity of the material.
- The material is put in the mixers and blended for 20 to 30 minutes, until it obtains a specific level of homogeneity.
- We collect the first sample weighing 1 to 1.5 kg, that is further sieved and manually blended.
- We collect the current sample weighing 30g to 100g.
We blend materials as long as necessary to obtain the optimal homogeneity.
