How to Replace the Sparge Cell on an OI Eclipse 4660 | Purge-and-Trap Maintenance
A contaminated sparge cell can become a hidden source of purge-and-trap problems.
In this video, I show how I replace the sparge cell on an OI Eclipse 4660 purge-and-trap concentrator.
I cover:
• Accessing the sparge cell assembly
• Disconnecting the existing cell
• Removing the dirty or contaminated sparge cell
• Installing the replacement cell
• Reconnecting the fittings and tubing
• Checking the final installation before returning the system to service
Because the sparge cell is in direct contact with the sample, contamination can build up over time. When the cell becomes dirty enough, replacement may be necessary to maintain clean sample handling and reliable VOC performance.
This video focuses on the physical replacement procedure.
