Phenomenex Inc.，世界领先的色谱耗材制造商，推荐Gemini-NX C18，用于苛刻流动相条件下的新一代色谱填料。
除了强疏水选择性和高载样量之外，Gemini-NX与最初的Gemini产品相比，稳定性明显增加，有更高的分离度和更长的柱寿命。新的填料采用先进的TWIN-NX (Two-in-One)技术，在硅胶表面移植了一层独特的硅胶－有机层。先进的NX方法使用交联乙烷团，加强硅胶的强度和硬度，并扩大pH稳定性至1-12。Gemini-NX的稳定性使其有更长的柱寿命并能减少由于更换色谱柱而耽误的时间。
宽广的pH范围在流动相调节方面有更大的灵活性，能更灵活的调控离子型化合物的保留和选择性。因为多数药物化合物含离子型基团，Gemini-NX广泛应用于药物研发、方法开发和大规模的应用。
“Phenomenex因为Gemini的供应，是pH-LC分离技术的先锋，”Phenomenex的产品经理Jason Lam说道，“Gemini-NX会继续以它明显的性能优势居领先地位。”

UHPLC and HPLCHigh performance liquid chromatography (HPLC) and ultra high performance liquid chromatography (UHPLC), also known as UPLC, are analytical techniques used to separate, identify and quantitate components of complex mixtures including biological samples such as proteins and lipids as well as chemical mixtures of pesticides, drugs and oils. Both techniques are liquid chromatographic methods but differ by operating pressures (HPLC < 6000 psi < UHPLC ). Components of HPLC and UHPLC systems include columns, detectors, pumps, autosamplers and column heaters. Explore a range of UHPLC and HPLC columns for your specific sample needs including reverse phase, normal phase, ion exchange, HILIC, ion exclusion and size exclusion columns. For more specialized HPLC, explore FPLC, countercurrent LC and simulated moving bed systems.
