Abstract
WhenusingSplit/Splitless injectionports, analysts have a
wide varietyof liner geometries to choose from. Split
liners are designedwithmixing chambers and tortuous
flowpaths to fullyvaporize the sample into a
homogeneous vapor cloudbefore it reaches the split point.
Splitless liners usually are designed as straight tubes, with
alternate designs, such as a gooseneck restriction, which
help contain the sample cloud in the injector andminimize
the breakdown of compounds sensitive to catalytic
decomposition from contactwithmetal inlet parts. The
residence time of the sample in a splitless liner is
dependent on liner geometry, gas velocity, and sample
vaporization time.
