SSL Injector: Components
The SSL injector periodic maintenance includes:
• Replacing the SSL septum
Replace the septum at least after every 200 injections, or every time a problem related to
septum damage, or wear occurs.
See
.
• Cleaning or replacing the SSL liner
Check the liner for contaminants, debris, breakage, and proper installation.
The liner must be replaced depending on the number of injections performed, and the
characteristics of the samples injected. Typical symptoms will indicate that the liner must
be replaced. The most common is the appearance of tailing peaks in the chromatogram,
particularly for polar compounds.
See
“Cleaning or Replacing the SSL Glass Liner”
Tip
It is good practice to replace the septum every time you replace the glass liner.
