Phenomenex Inc., a leader in the research and manufacture of advanced technologies for the separation sciences, introduces Aeris – core-shell HPLC/UHPLC columns specially designed for the analysis of proteins and peptides. These high-performance columns deliver higher resolution and peak capacities than other bioseparation media, producing sub-2 micron results on any LC instrument. With virtually no bleed, Aeris columns are highly compatible with MS.
Aeris columns are offered in wide- and small-pore configurations. Aeris Widepore 3.6-micron core-shell columns are optimized for the separation of intact proteins and polypeptides, and are available in three selectivities – XB-C18, XB-C8, and C4. Because the 3.6-micron core-shell particles produce lower backpressures than traditional media, longer or coupled columns can be used to increase resolving power on both HPLC and UHPLC instruments.
Aeris Peptide 3.6-micron and 1.7-micron columns, designed with a small pore size, are recommended for the separation of low molecular weight peptides and for peptide mapping. The novel XB-C18 stationary phase provides the ideal surface chemistry for resolving peptides. Aeris Peptide 3.6-micron particles offer ultra-high performance at backpressures compatible with both HPLC and UHPLC instruments. On UHPLC systems, the 1.7-micron Aeris particles can deliver higher peak capacities than fully porous sub-2 micron columns.
