Check purity of collagen with HPLC? - (Apr/10/2006 )

I don't know much about HPLC, so here comes my question.
I've isolated collagen type II but I don't know if it's pure or that there are other collagen types in my sample. Can I check with a HPLC if my sample is pure for this collagen type?

you may be able to if you have the right column and purified standards of the various collagen types to confirm the separation.
