How to replace the copper split vent line on an Agilent 6890 GC split/splitless inlet. In this hands-on maintenance video, I show the process of replacing the split vent line, including: • Accessing the inlet plumbing • Disconnecting the old vent line • Removing the tubing • Routing the replacement line • Reconnecting the inlet • Reassembling the system The split vent line is easy to overlook during routine inlet maintenance because most of it is hidden inside the GC. Over ti

In this hands-on video, I show how I replace the split/splitless inlet EPC pneumatic module on an Agilent 6890 GC. This repair involves going beyond routine inlet maintenance and accessing the internal pneumatic system of the gas chromatograph. In the video, I cover: • Opening the GC and accessing the EPC module • Disconnecting the pneumatic and electrical connections • Removing the old split/splitless inlet EPC module • Installing the replacement module • Reconnecting the sy

In this hands-on GC maintenance video, I show how I replace the top shell weldment on an Agilent 6890 split/splitless inlet. The top shell weldment is part of the inlet assembly and can require replacement when it becomes damaged, contaminated, or no longer performs reliably after repeated maintenance. In this video I cover: • Accessing the split/splitless inlet • Removing the existing top shell weldment • Disconnecting the associated inlet components • Installing the replace
