Descrição geral

This Certified Reference Material (CRM) is produced and certified in accordance with ISO 17034 and ISO/IEC 17025. All information regarding the use of this CRM can be found on the certificate of analysis.

N-Nitrosodiethylamine belongs to the group of toxic nitrosamines, known to show carcinogenic, mutagenic, and hepatotoxic properties. It is formed as a byproduct during food processing, pharmaceutical processing, and water treatment. As a result, they are generally found in water, fish, meat, drug substances, etc.

Aplicação

The CRM can be used as follows:
  • Simultaneous analysis of N-nitrosodiethanolamine, N-nitrosodiethylamine, triethanolamine, diethanolamine in cosmetic samples using liquid chromatography-electrospray ionization-tandem mass spectrometry (LC-ESI-MS/MS)
  • Solid phase extraction of N-nitrosodimethylamine and N-nitrosomethylethylamine from eight sartans, ranitidine, and metformin and also the fortified products of these drugs, for quantification by gas chromatography-tandem mass spectrometry (GC-MS/MS)
  • Multi-residue analysis of seven restricted nitrosamines in two body creams and two shower gel samples by vortex-assisted reversed-phase dispersive liquid-liquid microextraction (VA-RP-DLLME) and liquid chromatography-mass spectrometry (LC-MS)
  • Quantitative analysis of four nitrosamines in four sartan drug substances— candesartan cilexetil, olmesartan medoxomi, irbesartan, and valsartan, by gas chromatography-tandem mass spectrometry (GC-MS/MS)
  • Determination of eight volatile nitrosamines in 28 popular meat product samples using ultrasonic solvent extraction combined with solid phase microextraction (SPME) and GC-MS

Questions

1–2 of 2 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.
