Abstract
Some modifications of the stannous chloride reduction method for the estimation of inorganic phosphate reported by Berenblum-Chain are suggested. By this method, it is possible to measure 25 
g l–1 of phosphorus /P/ as inorganic phosphate in the presence of macromolecules like deoxyribonucleic acid /100 g ml–1/, as compared to 200 g l–1 of P by the original method. If a larger sample volume /30 ml/ is used, even 5 g l–1 of P can be measured.
Abstract
A simple, low cost TLC scanner system for the characterization of 
-emitting radiopharmaceuticals is described. The TLC scanner has a linear response range of 
0.074 Mbq up to 
2.94 Mbq. The accuracy and reproducibility of measurement is better than ±5% (relative). The utility of this TLC scanner system is demonstrated by application to the radioanalytical evaluation of99mTc(dmpe)2Cl

preparations. A comparison with HPLC radioanalytical separations is made.
