General description

Ascentis 系列色谱柱是 Supelco 科学家推出的第四代 HPLC 色谱柱技术。Ascentis 系列色谱柱是以高纯硅胶为基质，孔径 100Å，硅胶粒径为 3、5 和 10 微米。该色谱柱用于小分子的应用，柱内径可从微径柱（1.0mm 内径）扩展到制备尺寸（50mm 内径）。该系列包括 C18、C8、苯基、Si 和内嵌极性基团相（反相酰胺）。

Ascentis C18 是特别稳定可靠的首选 HPLC 色谱柱，即使对于难以分离的化合物也能提供对称的峰形和出色的保留性能。

Application


  • Preparation of polar embedded C18 stationary phase for efficient separation of peptides and proteins in high performance liquid chromatography.: 本研究详细介绍了极性嵌入式 C18 固定相的开发，证明了其在分离肽和蛋白质方面的有效性。Ascentis® C18 HPLC色谱柱凭借其高分离效率而得到广泛使用——这对于蛋白质组学和生物制药应用至关重要(Ali et al., 2022)。

  • A dilute-and-shoot liquid chromatography-tandem mass spectrometry method for urinary 18-hydroxycortisol quantification and its application in establishing reference intervals.: 研究人员使用 Ascentis® C18 HPLC 色谱柱开发了一种灵敏的尿液 18-羟基皮质醇定量测定方法。该方法通过提供准确的参考区间，帮助开展临床诊断和内分泌学研究 (Zhao et al., 2022)。

  • A Comparative Study on Analysis of Ginsenosides in American Ginseng Root Residue by HPLC-DAD-ESI-MS and UPLC-HRMS-MS/MS.: 本比较分析利用Ascentis® C18 HPLC色谱柱分离和鉴定西洋参中的人参皂苷。 本研究重点介绍了该色谱柱在制药行业天然产物研究和质量控制中的应用(Hsu et al., 2022)。

  • Validation of a Rapid and Easy-to-Apply Method to Simultaneously Quantify Co-Loaded Dexamethasone and Melatonin PLGA Microspheres by HPLC-UV: Encapsulation Efficiency and In Vitro Release.: 本研究验证了一种使用Ascentis® C18 色谱柱同时HPLC定量 PLGA 微球中地塞米松和褪黑激素的 方法，为药物输送研究提供了强大的工具(Brugnera et al., 2022)。

  • Simultaneous determination of ivermectin, clorsulon and their related substances in an injectable finished product by a stability-indicating RP-HPLC method.: 采用Ascentis® C18 HPLC色谱柱开发一种稳定性指示方法，用于分析药物制剂中的伊维菌素和氯舒隆，凸显其在质量控制和法规遵从性方面的作用(Padivitage et al., 2022)。
