It may be possible for us to undertake the anaysis with lower quantities than the minimum specified above. Please email us at info@celignis.com to find out.

For some of these packages the volume of the sample (after grinding) is more important than the acutal weight. We recommend that, when filling out an order form (whether using the Microsoft Word document or the Celignis Database) you indicate what category the sample falls under (e.g. wood, compost, grass etc.) so that we can determine whether the amount of sample that you are planning to send would be sufficient.
