Hi Joao,
There are no pubic models at the moment.
However, we can guide you through all the steps of creating your own model.
Make sure you have access to proper amount of data – as much as possible and as varied as possible. This point is critical for the success of your collections. By data we mean both spectrum and meta-data (attributes). The meta-data should be obtained from a reliable source (such as an external lab or a different measurement device).
