PEER-REVIEWED ARTICLES
Chromatographic Modelling for LC Method Development in a Quality-by-Design Framework
This article describes ways to apply quality-by-design principles to build in a more scientific and risk based multifactorial strategy in the development of an ultrahigh pressure liquid chromatography (UHPLC) method for omeprazole and its related impurities.
Pyrolysis–GC–MS for the Identification of Polymeric Materials
A pyrolysis–GC–MS method enables direct analysis of solid or liquid polymers without sample pretreatment, as illustrated here for various materials, including a dental filling material and a car wrapping foil. |
