Applicazioni

Il formato di ammonio può essere usato per studiare tamponi biologici. Il formato di ammonio è stato usato in uno studio per sviluppare un metodo di cromatografia liquida a elevata prestazione selettivo e ultrasensibile per uno dei fitormoni volatili di segnalazione, l′acido jasmonico (JA). Il formato di ammonio è stato usato anche in uno studio per sviluppare e convalidare un metodo di cromatografia liquida a iniezione diretta-spettrometria di massa tandem-ionizzazione per elettrospray (LC-ESI-MS/MS) per determinare con facilità e rapidamente 13 derivati della fenilalchilammina.

Altre note

Componente tampone nella separazione e purificazione dei glicosaminoglicani da sistemi complessi tramite cromatografia di affinità con Polybrene[1].

Domande

1–3 di 3 domande  

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

    1 risposta

    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 risposta

    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. Why the COA doesn't contain expiry date? How to determine the expiry date of the chemicals

    1 risposta

    1. This product is not assigned an expiration date. It is assigned a recommended retest date of approximately 3.5 years after the quality release date. A recommended retest date is the time during which the product is expected to remain within established stability specifications, provided that it has been stored under defined conditions. After the Retest Date, product samples should be examined to ensure that the product is still in compliance with the established specifications.

      For more information, you may access the "Product Dating Information" document under "ADDITIONAL USEFUL DOCUMENTS ABOUT OUR PRODUCTS" at the bottom of the Quality Services page with this link: https://www.sigmaaldrich.com/US/en/life-science/quality-and-regulatory-management/quality-services.
