Leaking conductivity cell
1. Check the waste lines for blockage; trapped particles can plug the lines
and cause a restriction and/or leak. If necessary, clear the waste lines by

may overpressurize the cell, causing it to leak. If the problem continues,
contact Technical Support for Dionex products for assistance.
