The “Cellule Pièges” platform is a National Analytical Service, certified by the INSU-CNRS. Its aim is to process and analyze particulate samples from sediment traps, mesocosms, and various collection devices sampling the downward particle flux.

This platform offers a list of services to the scientific community: sample processing (including swimmer sorting, sample fractionation and freeze-drying); mass, carbon and nitrogen analyses (total and organic), and elemental inorganic element measurements (aluminum, calcium, phosphorus, biogenic and lithogenic silica).
