Possible cause | Solution |
---|---|
Leaking fitting | Locate the source of the leak. Tighten any tubing fittings or connections and replace them as needed (see Replace tubing and fittings). |
Broken liquid line | When replacing tubing and fittings, the replacements must be of the same length and internal diameter (see Replace tubing and fittings). |
Blocked or improperly installed line | Make sure that no tubing is crimped or blocked. For blocked waste tubing, verify that it is not elevated at any point after it exits the Dionex Inuvion IC System. Waste tubing lines use gravity to drain into the waste container. Replace any blocked tubing. For more information, refer to the suppressor manual. |
