What are the main (fundamental) limitations impeding the development of column materials in UHPLC like IEX, SEC etc.?

UHPLC is commercialized since 2004, but there are still far less columns available with sub-2 micron technology than there are for HPLC columns. Are there limitations regarding the development of...

Why are there not many ion-exchange columns with sub-2 particles?

I'm guessing that it is because conventional IEX uses non-porous particles (NPP), and with UHPLC sub-2 particles the focus is to decrease mass-transfer kinetics, which can not be improved much...

I've been using silica hydride (DH column) since 5 years and I'm very happy from its performance however, there is no sub 2um or core shell particles.

Joseph J. Pesek

At this time there are not sub 2 micron particles but they are available in 2.2 micron particle size. Much easier to work with and fewer problems than the sub 2 micron particles and have nearly the same performance
