Peptide loadability in peptide mapping applications can be like looking for a needle in a haystack. See which of the candidate chromatography columns is best suited for this application. Who will win: BEH, CSH or HSS? More info: http://bit.ly/2eLPY4m
Here's a link to the ACS paper that CSH cites, "High-Resolution Peptide Mapping Separations with MS-Friendly Mobile Phases and Charge-Surface-Modified C18" http://bit.ly/2fFJdly
