Method development is increasingly considering green chem-istry principles, especially in HPLC or UHPLC [1–3] because liquidchromatography is a technique using high amount of hazardousorganic solvents. This tendency leads to the definition of guidelinesfor green method developments [4–7]. Although such develop-ments advantageously reduce environmental impact, they remainlimited in the pharmaceutical industry, especially in quality con-trol. The main reasons are first, the regulation e.g., EuropeanPharmacopoeia monographs, in which the analytical methodsdescribed are usually not “green”, then, the lack of knowledge andexperience and, finally, the cost induced by a renewal of equipmentwith higher performances, e.g., an UHPLC instrument. However,green analytical methods result in a decrease of toxic reagent con-sumption and may lead to cheaper and faster methods and betteroperator safety. The adoption of green technologies or approachesby new users requires more resources to make it easier. A key con-tributor to this knowledge base expansion can be offered by theconcept of quality-by-design (QbD).
