General description

We are committed to bringing you Greener Alternative Products, which belong to one of the four categories of greener alternatives. Phosphoric acid-doped polybenzimidazole (PBI) membranes offer a cleaner path to energy by enabling high-temperature fuel cells that efficiently convert hydrogen into electricity with low emissions. Their durability and proton conductivity make them ideal for sustainable power systems. Click here for more information.

Application


  • Development of green micellar HPLC-DAD method for simultaneous determination of some sulbactam combinations used in COVID-19 regimen: This study presents a green analytical methodology utilizing micellar high-performance liquid chromatography with diode-array detection (HPLC-DAD). It is specifically employed for the simultaneous determination of sulbactam and other compounds in COVID-19 treatment regimens, showcasing an application of ortho-Phosphoric acid in adjusting the pH of the mobile phase to enhance analytical performance and separation efficiency (Ragab GH, Saleh HM, Abdulla NM, Bahgat EA, 2023).

Questions

1–2 of 2 Questions  
  1. How can I determine the shelf life / expiration / retest date of this product?

    1 answer
    1. If this product has an expiration or retest date, it will be shown on the Certificate of Analysis (COA, CofA). If there is no retest or expiration date listed on the product's COA, we do not have suitable stability data to determine a shelf life. For these products, the only date on the COA will be the release date; a retest, expiration, or use-by-date will not be displayed.
      For all products, we recommend handling per defined conditions as printed in our product literature and website product descriptions. We recommend that products should be routinely inspected by customers to ensure they perform as expected.
      For products without retest or expiration dates, our standard warranty of 1 year from the date of shipment is applicable.
      For more information, please refer to the Product Dating Information document: https://www.sigmaaldrich.com/deepweb/assets/sigmaaldrich/marketing/global/documents/418/501/product-dating-information-06-25-mk.pdf

  2. How is shipping temperature determined? And how is it related to the product storage temperature?

    1 answer
    1. Products may be shipped at a different temperature than the recommended long-term storage temperature. If the product quality is sensitive to short-term exposure to conditions other than the recommended long-term storage, it will be shipped on wet or dry-ice. If the product quality is NOT affected by short-term exposure to conditions other than the recommended long-term storage, it will be shipped at ambient temperature. As shipping routes are configured for minimum transit times, shipping at ambient temperature helps control shipping costs for our customers. For more information, please refer to the Storage and Transport Conditions document: https://www.sigmaaldrich.com/deepweb/assets/sigmaaldrich/marketing/global/documents/316/622/storage-transport-conditions-mk.pdf
