InstrAction develops and manufactures 'instrAction phases” as novel highly selective resins for chromatography. The proprietary technology enables the immobilization of a wide variety of functional ligands on a polymer network, coated on very different porous backbone materials. Small molecules as well as substances with high molecular weight are separated by highly selective reversible interactions. The high selectivity of an instrAction stationary phase is thereby reached by multivalent-multimodal interactions between target molecule and the functional ligands of the phase, similar to the lock-and-key principle. The company is located in High Tech Park Neckarau, in Mannheim and is certified according to certified according to DIN ISO 9001.
