When you say that you want to LC 500 mL's of honey i hope you mean as a solution with an appropriate eluant. If you indeed mean that, then the chart on the page suggests 30-40 mm diam. columns.
If you do intend to use a column for separating 500 mL's of some fb. amine, you'd better have a warehouse handy, because you are going to need a REALLY big column ;)
