Gemini HPLC columns

"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."
