Reprospher 100 C30-DE is a reversed-phase HPLC column from Dr. Maisch HPLC GmbH, based on high-purity, fully porous silica with a 100 Å pore size and bonded with long-chain triacontyl groups. The phase features an advanced deactivation process that suppresses residual silanol activity, improving peak shape and reproducibility — particularly for basic, hydrophobic, and planar compounds. Thanks to its extended alkyl chain, this column offers strong hydrophobic retention and improved shape discrimination. It is especially beneficial for the separation of structurally similar analytes such as carotenoids, geometric isomers, and long-chain lipophilic substances.
With its combination of enhanced shape selectivity and peak symmetry, this long-chain phase from Dr. Maisch HPLC GmbH is ideal for demanding reversed-phase applications involving lipophilic and closely related structures.
