一般描述

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。

应用


  • Preparation of polar embedded C18 stationary phase for efficient separation of peptides and proteins in high performance liquid chromatography.: This study details the development of a polar embedded C18 stationary phase, demonstrating its effectiveness in separating peptides and proteins. The Ascentis® C18 HPLC Column was utilized for its high separation efficiency, crucial for proteomics and biopharmaceutical applications (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.: Researchers used the Ascentis® C18 HPLC Column to develop a sensitive method for quantifying urinary 18-hydroxycortisol. This method aids in clinical diagnostics and endocrinological studies by providing accurate reference intervals (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.: This comparative analysis utilized the Ascentis® C18 HPLC Column to separate and identify ginsenosides in American ginseng. The study highlights the column′s application in natural product research and quality control in the pharmaceutical industry (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.: This research validates an HPLC method using the Ascentis® C18 Column to simultaneously quantify dexamethasone and melatonin in PLGA microspheres, offering a robust tool for drug delivery studies (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.: The Ascentis® C18 HPLC Column was employed to develop a stability-indicating method for analyzing ivermectin and clorsulon in pharmaceutical formulations, emphasizing its role in quality control and regulatory compliance (Padivitage et al., 2022).

  4. What is the storage solvent for Product 581324-U, Ascentis® C18 HPLC Column - 5 ?m particle size, L × I.D. 15 cm × 4.6 mm?

    The storage solvent is a ratio of 40:60 water:acetonitrile for this column.

  5. What is the Department of Transportation shipping information for this product?

    Transportation information can be found in Section 14 of the product's (M)SDS.To access the shipping information for this material, use the link on the product detail page for the product. 

  6. What flow rate should I use with Ascentis® Express HPLC Columns?

    Based on the minimum in the van Deemter curves, higher flows than 5um particle columns are required in order to maximize Ascentis Express column efficiency. The suggested starting point for flow rate for Ascentis Express columns: 1.6 mL/min for 4.6 mm ID;  0.8 mL/min for 3.0 mm ID; and 0.4mL/min for 2.1 mm ID.

  7. Can Ascentis® Express HPLC Columns be used for LC-MS?

    Express Fused-Core™ particles were designed with LC-MS in mind. Even extremely short column lengths exhibit sufficient plate counts to show high resolving power. The flat van Deemter plots permit resolution to be maintained at very high flow rates to maximize sample throughput. All Ascentis stationary phases have been evaluated for MS compatibility during their development, and the Express phases are no exception. You can expect extremely low column bleed and background while maintaining longest possible column lifetime. A bonus of Ascentis Express columns for high throughput UHPLC and LC-MS is that they are extremely rugged and highly resistant to plugging, a very common failure mode for competitor columns.
