1952 Nucleonics Mar. 56/1 When the radiochromatogram is plotted as net rate of count against distance along the strip, w [= the total weight of labelled component] is proportional to the area enclosed by the relevant part of the curve.
1972 Physics Bull. May 298/1 A unique rapid imaging system which promised to shorten the time to locate the radioactive regions on thin layer radiochromatograms.
1988 L. Stryer Biochem. (ed. 3) xxii. 534 The radiochromatogram of the algal suspension after seconds of illumination was so complex..that it was not feasible to detect the earliest intermediate in the fixation of CO2.
