AN IMPROVED TWO-DIMENSIONAL SCANNER FOR RADIOCHROMATOGRAMS

Abstract

An improved scanner for two-dimensional radiochromatograms has been designed. This scanner prints permanent facsimiles on electrosensitive paper in considerably less time than is required for conventional X-ray film autoradiography. The practical limit of detection is of the order of 35 c.p.m. above background for C¹⁴ although compact spots assaying as low as 20 c.p.m. can be readily detected visually on the facsimile.
