Descripción general

Ascentis Express Peptide ES-C18 columns are specifically engineered to separate higher molecular weight compounds such as peptides and small proteins. These columns contain advanced Fused-Core particles that have larger pores (160 Å versus 90 Å in standard Ascentis Express), bonded with sterically-protected C18 ligands to provide extra stability (ES) at very low pH (< 1) and high temperatures (up to 100ºC). This greatly expands the application range for Ascentis Express columns.

Certificado de Análisis

Certificado de origen

  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. What is special about Ascentis Express?

    Ascentis Express columns provide a breakthrough in HPLC performance. Based on Fused-Core particle technology, Ascentis Express provides the benefits of sub-2 μm particles but at much lower backpressure.  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. How do I find price and availability?

    There are several ways to find pricing and availability for our products. Once you log onto our website, you will find the price and availability displayed on the product detail page.
