Fig. 1From: A new two-strip TLC method for the quality control of technetium-99m mercaptoacetyl-triglycine (99mTc-MAG3)Example chromatogram of Ph.Eur. HPLC analysis of 99mTc-MAG3. Hydrophilic compounds occur < 4.0 minutes, 99mTc-MAG3 is identified at about 4.5 minutes, lipophilic compounds are attributed to the region > 6.0 minute. 99mTc-MAG2 and 99mTcO4 are the main impurities. 99mTc-tartrate elutes as the first peak followed by small peaks of precomplexesBack to article page
