Why is particle size distribution important?

  • Size and distribution of the silica particles effect the packing efficiency of the columns and therefore process performance.
  • The higher the packing density, the higher the surface area, the more interaction between eluent and separation material resulting in higher efficiency separation. However, the higher the packing density, the smaller the mean particle size is and therefore the higher the backpressure will be.
