a chromatographic technique in which an unknown substance is applied to a chromatographic support together with one or more known compounds, in the expectation that the relative behaviour of the unkno, a 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, meetod, mille puhul uuritav ekstrakt jagatakse kaheks, üks osa ekstraktist kromatografeeritakse kohe, teisele osale lisatakse enne kromatografeerimist mõõdetava analüüdi standardit, mille hulk on lähe
