This uniform particle size standards minimize the response of analytical systems to shape effects and are excellent when a NIST traceable size standard with a very low standard deviation is required. Particles from 1 to 160 µm are made of polystyrene (PS) in suspension.
Particles from 200 to 1000 µm are made from polystyrene cross-linked with divinylbenzene (PSDVB) as a powder.
