Purification of X-ray contrast agents |
| abstract |
The present invention relates to a method of purifying iodinated X-ray contrast agents, in particular crude dimeric contrast agents such as iodixanol and ioforminol. More specifically, the present invention relates to the purification of such X-ray contrast agents by removal of monomeric impurities using membrane techniques. |
