- Comment "Zum Beweis der Identität einer Verbindung wird sie mit der vermuteten, authentischen Substanz zusammen chromatografiert. Eine Verbindung gilt als chromatografisch identifiziert, wenn sie unter mindestens fünf bis sechs unterschiedlichen chromatografischen Bedingungen nicht von der Testsubstanz unterscheidbar ist.Quelle: Thieme RÖMPP Online, Eintrag zu ""Cochromatographie"", Thieme, 2010, http://www.roempp.com/prod/ (12.07.2010)."

- Definition procedure in which the extract prior to the chromatographic step(s) is divided into two parts: Part one is chromatographed as such Part two is mixed with the standard analyte that is to be measured. Then this mixture is also chromatographed. The amount of added standard analyte has to be similar to the estimated amount of the analyte in the extract. Reference "2002/657/EC: Decision implementing Directive 96/23/EC concerning the performance of analytical methods and the interpretation of results CELEX:32002D0657/EN"
