This curve analysis allows: for centrifuge-based consolidation of suspensions: to obtain the concentration and pressure dependencies of specific cake resistance; for centrifuge-based ultrafiltration of solutions: to measure the resistance of the fouled membrane
  • to determine the compressibility of the filter cake formed at the membrane surface
  • and to evaluate the fouling mechanism. Measurements can be carried out in a wide range of solid pressure from 5 kPa to 500 kPa.

A broad spectrum of particle sizes from a few nanometres up to several micrometres can be detected with LUMiSizer without neglecting the minority populations of smaller or larger particles. Limitations are too high sedimentation/floating velocities of large particles.
