Difference between split and splitless liner
WebWhile these interactions can occur when using either split or splitless injections, liner inertness is especially critical for splitless injections. Splitless injections have lower total inlet flows, leading to longer liner residence times for analytes and therefore more time for adverse interactions to occur. WebApr 26, 2024 · Location.
