Table 4 Results of corresponding HPLC measurements at 3 different time points in comparison with SPE- method results from table 3. The SPC in force today does not mentioned which impurities are attributed to the individually eluted fractions on the SEP-PAK columns and the (99mTcO2)n is not taken into account (not measured).
