This article looks at the use of bracketing and matrixing to lower the number of stability samples required and, consequently, reduce the cost of sample production, testing and management. There is a common misconception that regulatory authorities will not accept such methods, but there is actually an International Conference on Harmonization guideline (ICH Q1D) on the subject. In fact, many of these designs have already been accepted and FDA members were among the first to describe matrixing.

A limit test using ion mobility spectrometry (IMS) has the potential to dramatically reduce the time required for cleaning verification and cleaning method development. The traditional approach to cleaning verification, often using HPLC, is relatively resource intensive and can lead to significant delays in reporting results. The main advantage of IMS is that results are seen virtually instantaneously, so any necessary re-measurement can be done very quickly. If the results demonstrate cleanliness, production can resume in a matter of hours not days.
