DOI: 10.1002/jssc.202001136 The cover picture shows the attributes of a mixed‐mode reversed‐phase/anion‐exchange stationary phase designed for separations of mixtures containing polar acids. The stationary phase is based on bridged‐ethyl hybrid organic/inorganic particles, which allows the use of a broader mobile phase pH range vs. silica‐based materials. This opens up a greater range of mobile phase selectivity options for method development. The batch‐to‐batch reproducibility is comparable to state‐of‐the‐art C 18 stationary phases.
