Although even narrower peaks are produced in techniques of ‘very fast’ and ‘ultra fast’ GC, these were not further probed here and would require more appropriate conditions of faster detector electronics to properly examine. It is also unknown if peak tail may arise when using such very fast FPD response in a mode such as GC × GC operation. Still, given that other FPD methods are compatible with such high-speed GC separations [46], it seems reasonable to anticipate that the SS mFPD should be as well
