Why Use Narrow ID Liners?

Why Use Narrow ID Liners?

 The low carrier gas flow rates used with fast columns can cause band broadening in the injection port, especially during splitless injections.

If a liner with a small internal volume is used, the velocity of the carrier gas through the liner will be increased. This reduces the amount of time the sample spends in the injection port minimizing band broadening.

A liner with an internal diameter of 2mm or less needs to be used in splitless mode to reduce mass discrimination.

SGE's liner selection tool helps you select the right inlet liner for your analysis

The tool also includes a handy Vapor Volume Calculator that checks if you are injecting too much for a particular liner.  It can help you avoid the ghost peaks, injector contamination, and quantitation errors associated with Flashback.
