ReproSil-XR 120 Phenyl from Dr. Maisch HPLC GmbH is a high-purity silica-based HPLC column with a 120 Å pore size and a phenyl-bonded stationary phase. This phase combines aromatic π–π interaction capability with moderate hydrophobic retention, providing unique selectivity for aromatic and conjugated compounds compared to conventional alkyl-bonded phases. Its balanced interaction profile makes it ideal for method development and for separating compounds with subtle structural differences, such as isomers and aromatic derivatives.
ReproSil-XR 120 Phenyl columns from Dr. Maisch HPLC GmbH deliver distinct aromatic selectivity and high performance – the ideal choice for challenging HPLC separations involving aromatic compounds.
