In 1986, Rodolphe Margraff, a researcher at the Rhône-Poulenc Pharmaceutical Research Center in Vitry sur Seine (94), succeeded in purifying active ingredients by CPC where the preparative HPLC had failed (purification of the anti-cancer drug Docetaxel (Taxotère) ). He realized that the CPC allowed a reduction of the purification costs (from 2.5 to 3 times) thanks in particular to a reduced consumption of solvents (of 10 times) and to the absence of the silica support which was very expensive.
Noting that only low-capacity devices intended for laboratory experimentation existed and that no production device was available, Rodolphe Margraff decided to create the PARTUS brand in order to innovate and develop a reliable and usable machine in truly industrial conditions such as 24 hour continuous operation.
