Abstract
The invention relates to industrial preparation of contrast agents, and further to an improved process for the purification of contrast agents. In particular, it relates to a process for reducing the salt content of compositions comprising an MR contrast agent or an X-ray contrast agent, such as a non-ionic iodinated monomeric compound or a non-ionic iodinated dimeric compound.
Claims16
A process for the preparation of a composition comprising a contrast agent in a carrier, the process comprising the step of desalinating the composition by electrodeionization (EDI) using a wafer based EDI device.
A process as claimed in any of claims 1 to 3 wherein the contrast agent is selected from iohexol, iodixanol and ioforminol.
