In the nanotechnology arena, competition and technical development are key characteristics. Continuous update and refinement of particle (surface) properties is needed to meet to client demand. On the other hand there are two good reasons for standardisation, i.e. quality control and Human Safety & Environment (HSE) issues. It is our policy to integrate HSE issues into quality control to minimize risks of working with materials of ill-defined properties. At the same time these properties are well controlled for the sake of quality control and product performance.
