Selecting the correct MMI liner
Split liner
A good liner for split mode operation will offer very little restriction to the split flow path
between the bottom of the liner and the inlet body and between the outside of the liner and the
inside of the inlet body. The preferred Agilent split liner, part number 5183-4647, incorporates a
glass positioning bead on the bottom to facilitate this. It will also incorporate glass wool or
some other source of surface area inside the liner that provides for complete sample
vaporization across the boiling point range of the sample. Select an appropriate liner from
Table 29.
Splitless liner
The liner volume must contain the solvent vapor. The liner should be deactivated to minimize
sample breakdown during the purge delay. Solvent vapor volume can be reduced by using
Pulsed Splitless mode. Use the Vapor Volume Calculator to determine vapor volume
requirements.
Vapor volume < 300 µL Use 2 mm liner (250 µL volume), 5181-8818 or similar.
Vapor volume 225 – 300 µL Consider pulsed splitless mode to reduce vapor volume.
Vapor volume > 300 µL Use 4 mm liner, 5062-3587 or similar.
Vapor volume > 800 µL Consider pulsed splitless mode to reduce vapor volume.
For thermally labile or reactive samples, use G1544-80700 (open top) or G1544-80730 (top
taper) liners.
