Tritium labelled compounds on paper chromatograms are detected, localized, and the ratios of their activities determined precisely with a windowless scanner. Filter paper strip is pulled, by a wheel driven by a synchronous motor, between two windowless, flow, Geiger-Muller counters. The flow of argon saturated with propanol vapor provides an air-lock. Pulses from the Geiger tubes are fed to a precision, linear ratemeter and recorder with chart speed equal to that of the filter paper strip. The efficiency of counting tritium is low. The sensitivity limit lies aroung 3 m mu c/cm/sup 2/ of Whatman No. 1 filter paper. (auth)
