SSLBKF Injector Components
The SSLBKF injector periodic maintenance includes:
• Replacing the SSLBKF 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 replying the SSLBKF 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.
