I've had good luck with a Pharmacia (no affiliation) product, SizeSep 400.
which is designed (or at least marketed for) the purpose you describe.  It
will get rid of the linkers and dNTPs, and also size select for >400 bp.
If you want to have things smaller than that, then this product probably
isn't what you're looking for.
