A very useful construct in engineering and analytical chemistry is the concept of a time-invariant linear system. The properties of the system (as for a mathematical function) are defined by a relationship between the response and the excitation, and ...

One issue that has become clear to us throughout courses, workshops, seminars, and various talks on the subject of method validation, is that while many people talk the language, sometimes the individual method validation terms mean different things to different people. While the actual protocols, or experimental details used to measure or evaluate method validation can vary, it's a good idea to have a common understanding of the underlying terms. In this month's installment of "Validation Viewpoint," we have compiled glossary of method validation terms as they pertain to chromatography.
