Aplicación

Sucrose Optical Rotation standard reference material (SRM) is intended for use as a saccharimetry standard, used to calibrate polarimetric systems.

Características y beneficios

  • Accompanied with certificate documenting NIST-certified values of sucrose mass fraction and non-certified values of carbon and hydrogen mass fraction.
  • Certified chemical purity values are determined using a quantitative 1H-nuclear magnetic resonance spectroscopy (q1H-NMR).
  • Certified values are metrologically traceable to the International System of Units (SI) of mass.
  • The NIST certificate is provided with storage and use instructions.

Questions

1–3 of 3 Questions  
  1. 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

  2. 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

  3. 현재는 단종된 17F와 17G의 차이를 문의드립니다. 단순 용량 차이일까요, 또는 성분에 차이가 있을까요?

    1 answer
    1. The NIST17F is no longer available. The product has been replaced by NIST17G. In comparing the certificates offered by the NIST there does not appear to be any difference. Both products are packaged in quantities of 60 grams. Further details would have to be obtained through the supplier. See the link below to the NIST product page:
