Comparison of biphenyl and other aromatic stationary phases

(U)HPLC/SFC Application

Many of our columns feature aromatic ring-based stationary phases with strong π-π interactions, notably our πNAP (naphthylethyl) and PYE (pyrenylethyl) columns. Several other companies produce similar columns using a biphenyl phase, which has become a popular alternative to C18 in recent years. Here, we compare these columns for several kinds of analysis.
