Sigma-Aldrich division Supelco this week launched the Ascentis Express Peptide ES-C18 HPLC column.
The column is based on a new 160 angstrom fused-core particle design, Supelco said in a statement, and added the design "exhibits very high column efficiency, providing a stable, reversed-phase packing with a pore structure and pore size that is optimized for reversed-phase HPLC separations of peptides and proteins."
The columns can be used to speed up the identification, purity monitoring, and quantitative analysis of peptides, Supelco said. Additional applications include peptide mapping, natural and synthetic peptide analysis, and oligonucleotide analysis.
