  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 does DB stand for in Supelcosil LC-8DB HPLC column, Product 58354?

    DB stands for "deactivated base", and refers to the base treatment of the packing in this column. Without this treatment, basic compounds will adsorb to active acidic silanol sites.  If starting a new method, Supelco suggests using a new-technology/pure-silica C8, such as the Ascentis C8.

  4. Can the Supelcosil LC-8DB HPLC column, Product 58354, be used for acidic compounds?

    No, it is base treated, therefore acidic compounds will be adsorbed by the base treatment, resulting is peak tailing.  

  5. Do you have a cleaning procedure for Supelcosil LC-8DB HPLC column, Product 58354?

    Yes.

  6. 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. You can contact any of our Customer Sales and Service offices to receive a quote.  USA customers:  1-800-325-3010 or view local office numbers.
