  • This webinar presented by Dr. Anne Virden, covers method development for samples measured in dry dispersion.
  • Dry dispersion offers the advantage of measuring larger sample masses much more quickly as well as different disperser options for fragile or robust samples.
  • Discover the processes you can use to assess the state of dispersion and reproducibility of dry measurements to enable you to set up a robust method.
