very excellent column for research and development
Application Area: Drug analysis by HPLC
"Column is very useful with a wide pH range of mobile phase. Column life is also excellent after so many injections. Separation of peaks are very nice."

A great column for small molecules with ionizable groups.
Application Area:Analysis of small molecules
"These columns can be used over a wider range of pH, which makes them much more versatile than the classical silica-based columns. Furthermore, they come in a brad range of bonded phases, particle sizes, pore sizes and dimensions. i found the Gemini SAX particularly useful because I can combine both the ionic strength and the pH of the mobile phase, to impact the selectivity, thus achieving optimal resolution of all my analytes with shorter run times."

"I have worked with Phenomenex Gemini C18 and Phenomenex Phenyl C6 and obtained very good separation of compounds with aromatic rings, namely phenolics in plant materials (mobile phase of 01.% formic acid + acetonitrile). Phenyl C6 is better if you aim a good selectivity between isomers."
