Questions

1–8 of 8 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/449/386/product-dating-information-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

  3. How was the titration done for 425044, and how was the percent for the COA obtained?

    1 answer

    1. The quality level of the product is 100, no information can be provided on the tests that are run on the COA.

      Helpful?

  4. Please provide information on whether the 10-15% concentration of this solution is by weight/weight, volume/volume, or something else.

    1 answer

    1. The chlorine concentration is reported as Weight/Weight (W/W) for this product.

      Helpful?

  5. Is this material %(W/V) or %(W/W) for the available chlorine titration.

    1 answer

    1. It is % (W/W).

      Helpful?

  6. How is available chlorine tested?

    1 answer

    1. To analyze for available chlorine, a sample of sodium hypochlorite is added to a solution of potassium iodide in the presence of acid to liberate iodine.  The liberated iodine is titrated with standardized sodium thiosulfate.

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

    1 answer

    1. 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.

      Helpful?

  8. What is the definition of available chlorine?

    1 answer

    1. Available chlorine is a measure of the bleaching power of a substance. Available chlorine is defined as chlorine capable of releasing an equivalent amount of atomic oxygen according to the following reaction equations.Cl2 + 2OH- --> OCl- + Cl- + H2O  (eqn. 1) HOCl --> HCl + ½ O2  (eqn. 2)
