Hello Walt

Do yourself a favour and stick to a column designed for 
peptide/protein analysis. We have found the Vydac 218TP columns 
to be robust and reliable. Also the pore size plays a major 
role in the separation of tricky peptide digests.  Ask you 
Waters rep for a copy of "Doctor Tom's Guide to the 
Undocumented Oral History of Peptide Separation Fokelore" - 9 
pages of distilled wisdom!

Good Luck
