IMPURITIES IN COMMERCIALLY PREPARED TRITIATED FOLIC ACID
A check on the purity of a commercially available tritiated folic acid, specified by the manufacturer to be 100% pure by dilution analysis and chromatography, revealed that only 50% of the radioactivity corresponded to the folic acid absorbent area on paper chromatograms. (C.H.)
