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.
NOTE
Pulsed split and pulsed splitless modes are not supported on EPR
(electronic pneumatics regulation) equipped GCs.
