Witrynaimpurities were supported by the batch data2. The analytical method for the determination of clethodim in the TC is a reverse phase HPLC with UV detection. The … Witryna22 lip 2024 · The radioactivity of impurity radionuclides is normally 3–9 orders of magnitude lower than 99m Tc in the 99m Tc eluate. It is impossible to directly measure these impurity radionuclides using radiometric methods, removal of most of 99m Tc is needed before measurement of other gamma emitters. WitrynaActive substances often contain impurities which originate from manufacturing. According to the definition of Regulation ( EU ) No 283/2013, impurities in the technical active substance are considered relevant if they are particularly undesirable because of their toxicological, ecotoxicological or environmental properties. cindy goodsell
