Celeris™ Ethyl Pyridine

Ethyl pyridine phases are the workhorse phases for preparative and process scale SFC purifications. Celeris 2EP (2-ethyl pyridine) and 4EP (4-ethyl pyridine) media is designed to be highly reproducible based on tight product specifications and low metal content. Celeris 2EP is especially well-suited for separation of acidic compounds and exhibits broad selectivity towards a variety of other compound types. The Celeris 4EP phase offers alternate selectivity to the 2EP phase. Celeris 2EP and 4EP SFC columns deliver high performance separations comparable to competing ethyl pyridine phases at a much lower price.

Celeris ethyl pyridine phases provide similar or better separation than competing EP phases
