General description

Visit our Sensor Applications portal to learn more.
TISAB, in general, is mixed with samples, as it helps in maintaining the ionic strength and pH constant. It is mainly used to decomplex metal-F complexes. TISAB II can be prepared using NaCl with glacial acetic acid, 1,2-Cyclohexylenedinitrilotetraacetic acid and NaOH.[1] It also has high concentrations of cation chelators that hydrolyse fluoride-ion pairs to form fluoride ions.[2]

Application

TISAB II is used to determine total fluoride concentration using fluoride ion-sensitive electrode from dental varnish.[2] It may also be used for the fluoride determination in presence of Fe(III) and Si.

Questions

1–3 of 3 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.

  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
