SIBS provides grinding service for almost any sample materials, using Retesch Oscillating Mixer Mill MM400 (for leaf, root, stem, , soil, fecal, blood, liver, and fish samples), Freezer Mill 6770 (for feather and hair), mortar and pestle (for salty soil), and scissors (for a small amount of samples such as insect and hair).
Homogeneity is very important for a better precision and accuracy of stable isotope analysis.
- We need at least 3g of samples. If you have samples less than 1g, contact us.
- Non-ground bulk samples can be sent in any containers. We provide glass vials.
- Sample IDs must be clearly written on the containers.
See photos below for good and bad examples
BAD: Coarse leaf sample with some fiber
GOOD: homogeneous leaf sample (all particles are the same size. No fiber)
BAD: Coarse feather sample (see difference particle sizes of white and brown materials)
GOOD: The same feather sample with above, but ground much better (smaller particle for both white and brown materials)
