A quantitative radio HPLC method for the analysis of radiolabeled99mTc compounds, in particular labeled antibodies or proteins, is described. The method is based on the quantitative re-oxidation of the reduced column absorbed99mTc species to pertechnetate using hydrogen peroxide. The pertechnetate is quantitatively eluted from the column. The method can be used as a stand alone technique for determining the true radiolabeling yield of labeled proteins/antibodies. The method has been automated for routine use and the typical analysis time is 30 min. © 1994.
