Description

An analytical technique using reversed-phase liquid chromatography was developed for the determination of urea at quantities as low as 1 ng to quantitate the amount of non-labelled urea produced during the synthesis of no-carrier-added [sup(11)C] urea starting from sup(11)CNsup(-). As a result, the specific activity of the [sup(11)C] urea thus prepared was calculated to be as high as 3.5+-0.8 Ci/μmol. (author)
