Purospher® STAR Phenyl HPLC columns show an enhanced selectivity compared to standard alkyl phases. They are the first alternative to RP-8 or RP-18 selectivities for separation of aromatic compounds, fatty acids, purines and pyrimidines due to π-π interactions. The new Purospher® STAR Phenyl columns are based on high purity silica particles providing symmetrical peaks for basic compounds, high stability and excellent reproducibility.

Supplier: Merck

Fast method development of complex samples across the pH range from 1,5 to 10,5 with different mobile phases and temperature conditions.
Purospher® STAR RP-18 endcapped HPLC columns are designed for universal use. Basic, neutral and metal-chelating compounds can easily be separated with simple mobile phases – naturally without peak tailing. Thanks to its outstanding performance and stability, Purospher® STAR RP-18 endcapped offers maximum flexibility in method development. Robust methods can be developed over the entire pH range from 1,5 to 10,5. High pH-stability allows the separation of strongly basic compounds with alkaline eluents. The combination of high purity silica, best all-round retention characteristics, outstanding pH stability up to pH 10,5, and suitability for up to 100% aqueous mobile phases, make Purospher® STAR RP-18 endcapped an all-round top performance column, almost universal in its range of applications.

Chromolith® DIOL columns are useful as an intermediate polarity media between C18 and silica. Diol functionalised media is less polar and can have different selectivity. Chromolith® DIOL can be used with a wide range of solvents in both normal and reverse phases. In normal phase mode, the diol phase provides an alternative selectivity compared to silica whilst additionally demonstrating longer retention times that help to obtain separation. In reverse phase mode, compounds such as water-soluble vitamins, sugars or amino acids are easily baseline separated using simple mobile phases. Chromolith® DIOL columns have long lifetimes within pH range of 2,5 to 7,5, high matrix tolerance and speed of analysis.
