Crystal Pharmatech scientists have been involved with numerous API particle size method validations and transfers spanning the entire project lifecycle from pre-clinical to supply. We have a wealth of particle characteristic understanding that results in established workflows for choosing the optimal particle size method for your particular system. We understand the language of "particle sizing" and know the inherent variability associated with each type of established technique. Additionally, we know how all established techniques compare to one another and can help with any type of validation or transfer that you require.
