To develop a MMI method that uses large volume injection
This topic provides a recommended way to change from a
splitless injection using a split/splitless inlet to a solvent
vent mode injection using a Multimode inlet (MMI). It applies
mainly to large volume injections (LVI) using a Multimode
inlet, but the concepts can apply to general MMI use. This
topic does not consider all items that can impact an
analysis, for example the liner, solvent, analyte boiling
points, or polarity. This topic also assumes knowledge of
your data system—when to save a method, how to start a
run, how to set up a single run, etc.
