网页2020年10月19日 · Description. Septa replacement is one of our most common tasks when doing routine GC inlet maintenance on our gas chromatographs. Fortunately, it is also one of the easiest! In this example, we replace the septum in an Aijiren gas chromatograph. The steps may vary on a different instrument or configuration.

网页2005年9月1日 · Figure 2 - Septum degradation (seen as ghost peaks). Following is a simple test that can be performed in the laboratory: Keep the column cold (30 °C) for 15 min, perform a blank run (no injection—only a temperature program up to 300 °C), and observe the baseline. After that run, cool the column to 30 °C again, keep it at 30 °C for 60 min
