Hold time studies

What is parallel & sequential HTS?

Hold time study, has to be carried out for intermediate products
For suppose if you want to carried out the study for 60days…

  1. Parallel study means without completion of the first batch study, second and third batches considered for the same study.
  2. Sequential study means, HTS has to be carried out after completion of first batch, start second batch and then third batch.
    Note: sequential study takes more time when compared to parallel study…
    **1/3rd of sequential time is sufficient for parallel study.
