  • Ferrous Wear Metal Measurement Made Easy with the FerroCheck

    Historically, one of the most cost-effective indicators of machinery health has been the analysis of ferrous debris in oil. Such analysis utilizes the ferromagnetic properties of generated debris to perform the analysis. Since nearly all wear debris contains ferrous material (in particular iron), an abnormal increase in the amount of debris can be directly correlated to abnormal machinery ...

  • The binding of metal ions to molecularly-imprinted polymers

    Imprinting polymerization is a flexible method to make resins specific for different compounds. Imprinting polymerization involves the polymerization of the resin in the presence of a template, here cadmium ions or arsenate. The template is then removed by washing, leaving specific binding sites in the resin. In water treatment, the removal of toxic metal ions is difficult due to the limited ...
