Polyurethane foam can be used in chromatographic separation of the column, a column of permeability, easy to install the simple, can match the solvent, the higher the capacity of the column and so on. According to the electron micrograph, the polyurethane foam is a polymer composed of 1-10um spherical particles, which determines the excellent mass transfer rate and high capacity of the polyurethane foam, whether it is used for rapid chromatographic separation or Preparation of chromatography, have the potential for superiority.
Another application of polyurethane foams in analysis is the use of materials for pH meters, such as elastomeric joint springs on pH meters, package air valves for sealed cavities and components such as watertight gaskets and anti-splash baffles The
