title: Factors influencing paper chromatographic analysis of technetium-99m phosphorus compounds: concise communication.
abstract: A single-paper chromatographic system has been developed, capable of resolving Tc-99m dioxide, [99mTc] pertechnetate and Tc-99m phosphorus compounds. The best separations are obtained with CM82 paper developed in 0.5 m naCl, and 3MM or ashless No. 40 paper developed in 1 M sodium acetate buffer. In these systems, 99TcO2 remains at the origin, while 99mTcO4--and Tc-99m phosphorus compounds move with Rf values of 0.56--0.75 and 0.80--1.0, respectively.
