Research and development, an essential phase at INTEROR

INTEROR's R&D teams are based in Calais, where our engineers and doctors work with customers on the development of the best solutions. INTEROR offers complete services from the early stages of benchtop testing, including the development of analytical methods, to industrial manufacturing where the relay is taken over by the industrialization teams. The technical platform has many analytical devices: for standard analyses (GC, HPLC, melting point, titration...) and also more specific analyses including the determination of impurity structures (NMR, IR, UV spectrum).
