  • Particle removal efficiency of Nano alumina fiber filters

    Particle removal efficiency of Nano alumina fiber filters

    A 2 nanometer alumina fiber is combined with a microglass fiber to produce a nonwoven filter. Its pore size is 2 microns, yet it is functionally rated at 0.03 microns. Data are presented showing dirt holding capacity and filtration efficiency for ...

  • Virus and protein separation using Nano alumina fiber media

    Virus and protein separation using Nano alumina fiber media

    Nano alumina fibers, 2 nm in diameter and approximately 0.3 μm long are electroadhesively grafted to a microglass fiber. A non-woven media is formed that has a zeta potential of ~+40 mV at pH 7. The media is capable of high retention of submicron ...

  • Non-woven electrostatic media for chromatographic separation of biological particles

    Non-woven electrostatic media for chromatographic separation of biological particles

    The filtration and separation of biological particles has been estimated as 40% of the cost in the manufacture of pharmaceuticals. Liquid chromatography that is the principal method for separating biological particles uses a permanent phase of ...

  • High performance microbiological filter

    High performance microbiological filter

    Filtration processes are a large cost component of pharmaceutical manufacture. The particle retention efficiency, particle capacity of the filter and the liquid flux all impact on product cost. A non woven electropositive filler media has been ...
