• Objective of the seminar
•  
• Particle sizing and surface area measurements are
  commonly used in many industrial environments
  including pharmaceuticals. Practicability,
  reliability and transferability are mandatory
  characteristics of all analytical methods and
  represent the basis for a correct validation of
  those methods that are used for regulatory
  purposes.
• ISO guidelines, are already available for laser
  diffraction, PCS and surface area measurements by
  BET and similar guidelines are now in preparation
  on porosimetry, image analysis, light interaction
  and gravitational methods.
• In the pharmaceutical field compliance with
  compendia (namely pharmacopoeia) test methods and
  relevant guidelines is also required. Moreover
  compendia methods for particle size and surface
  area measurements are presently the object of
  International Harmonization Procedure.
• All considered, the present seminar is focused on
  the most commonly used techniques for the
  microstructure characterisation of powders,
  namely laser diffraction, surface area
  measurements by BET and porosimetry, with the aim
  of highlighting the critical points and
  elucidating how ISO standards can facilitate a
  correct use of equipments and a safe
  interpretation of experimental data.
• The seminar is directed to the manufacturers of
  bulk materials as well as of finished products,
  to the operators in quality control and quality
  assurance activities and to people involved in
  the preparation of registration dossiers.
