General description

The Ascentis family of columns is the fourth generation of HPLC column technology from Supelco scientists. Ascentis columns are bonded on high purity, 100 Angstrom silica including 3, 5, and 10 micron particle size. Columns are designed for small molecule applications and are scalable from micro columns (1.0 mm I.D.) to preparative dimensions (50 mm I.D.). The family includes C18, C8, Phenyl, Si and embedded polar group phase, RP-Amide.

Ascentis RP-Amide is a new generation ultra low bleed, embedded polar group (EPG) phase that provides orthogonal selectivity and increased resolution for HPLC and LC-MS analysis of polar compounds. The Ascentis RP-Amide is the first choice in embedded polar group HPLC phases.

Application


  • A validated UHPLC method for the determination of caffeoylquinic and di-caffeoylquinic acids in green coffee extracts using an RP-Amide fused-core column.: This study presents a validated Ultra-High-Performance Liquid Chromatography (UHPLC) method employing an RP-Amide fused-core column for the quantitative determination of caffeoylquinic and di-caffeoylquinic acids in green coffee extracts. The method demonstrated excellent precision, accuracy, and sensitivity, making it a valuable tool for the analysis of these bioactive compounds in complex matrices. The research highlights the utility of the Ascentis® RP-Amide HPLC Column in enhancing the resolution and efficiency of chromatographic separations in analytical chemistry applications (Fibigr et al., 2018).

Features and Benefits

  • Excellent retention and peak shape for polar compounds
  • 100% aqueous compatibility
  • Ultra low bleed, LC-MS compatible
  • Unique selectivity

  1. Which document(s) contains shelf-life or expiration date information for a given product?

    If available for a given product, the recommended re-test date or the expiration date can be found on the Certificate of Analysis.

  2. How do I get lot-specific information or a Certificate of Analysis?

    The lot specific COA document can be found by entering the lot number above under the "Documents" section.

  3. Can I use Ascentis Express on a UHPLC system?

    Yes.  Ascentis Express columns are packed in a way making them suitable for these ultra high pressure instruments.  In fact, Ascentis Express outperforms sub-2 μm micron columns on many applications since Ascentis Express provides the benefits of sub-2 μm particles but at much lower back pressure.  These benefits include the capability of providing fast HPLC and higher resolution chromatography.  The Fused-Core particle consists of a 1.7 μm solid core and a 0.5 μm porous shell.  A major benefit of the Fused-Core particle is the small diffusion path (0.5 μm) compared to conventional fully porous particles. The shorter diffusion path reduces axial dispersion of solutes and minimizes peak broadening.

  4. What solvent should Product No. 565325-U Ascentis RP-Amide HPLC Column  be stored in?

    Product No. 565325-U should be stored in 100% acetonitrile after any buffers have been flushed out.

  5. What is the Product No of the guard column for Product No. 565325-U Ascentis RP-Amide HPLC column?

Liquid chromatography-tandem mass spectrometry (LC-MS/MS) method was used for simultaneous quantification of tolterodine and its metabolite 5-hydroxy methyl tolterodine in rat plasma. Tolterodine-d6 and 5-hydroxy methyl tolterodine-d14 were used as internal standards (IS). Chromatographic separation was performed on Ascentis Express
