Solid paper written by a SME in pharmaceutical analysis, he has a deep understanding on the validation process as it applies to the pharmaceutical industry - in addition stability indicating methodology is a critical step in drug development. LCGC just published this very applicable whitepaper. It was invited to help review and edit, it was so well written I didn’t have much to contribute or change. Although Pharma focused a lot of the information can be applied to other industries.

Some takeaways from this paper- include the following on method robustness:

Typical parameters that can be adopted for any HPLC method being developed and evaluated for robustness. Definitely including solution stability- CRM-certified reference materials and over a course of study period- i.e. 7 days solution stability (sample).
