Optically pure L-valine was labelled with tritium by the Wilzbach method. Only 4 of the activity of the radiochemically pure valine was found in D-valine. This figure was determined by reverse isotope dilution. The suitability of this method for valine was tested, wich good results, with DL-valine

Optically pure amino-acids were labelled with tritium by the Wilzbach method. The percentage of radioactivity found in the opposite enantiomer was determined by reverse dilution analysis. After tritiation of L-phenylalanine, D-phenylalanine, L-tyrosine, L-proline, D-proline, L-glutamic acid and L-al
Some local anaesthetics and amino acids were labelled with tritium by the microware discharge modification of the Wilzbach technique. The jollowing substances were investigated: local anaesthetics: carbocaine, citanest, I-cocaine, tetracaine and xylocaine; amino acids: glycine, DL-u-alanine, DL-Leu
