Table 3 Table showing the RCP of 99mTc-MAG3 with the SPE-method, resulting from different elution rates applied. The cartridge was also measured (not requested in SPC 2003) for quantification of (99mTcO2)n which is retained on the cartridge

From: A new two-strip TLC method for the quality control of technetium-99m mercaptoacetyl-triglycine (99mTc-MAG3)
