<< We want to try some hilic coupled to ms, using capillary columns (no larger
than 500 microns diameter). Is there a commercial source for prepacked
columns that someone out there has used successfully in any application
(not just coupled to mass spec)?

Well, you could try us; we invented HILIC. I imagine you saw the
presentations at the ASMS meeting on HILIC-MS/MS of amino acids, HILIC-ESI of
NAD, etc. These all used columns of our PolyHYDROXYETHYL Aspartamide
material. These are available in i.d.'s of 0.5-, 1.0-, 2.1-mm and larger.
