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.

Application
- Determinazione simultanea di nove importanti vitamine liposolubili― acetato di retinile, palmitato di retinile, retinolo, α-tocoferolo, α-tocoferil acetato, colecalciferolo, ergocalciferolo, fillochinone, menachinone in vari prodotti alimentari commerciali mediante cromatografia a fluido supercritico abbinata a rivelazione con spettrometria di massa.
- Ottimizzazione di un metodo cromatografico a fluido supercritico (SFC) per la stima simultanea di vitamine liposolubili (FVS) in campioni di olio di semi di canapa e di olio di pesce di scarto, in combinazione con un rivelatore a schiera di diodi (DAD)
- Separazione e quantificazione mediante HPLC di esteri di β-carotene e vitamina A ed E in campioni di latte in polvere per neonati con rivelazione a fluorescenza (FLD)
- Analisi di campioni di olio da cucina per la determinazione di vitamine e carotenoidi liposolubili utilizzando un metodo di cromatografia di convergenza ad ultra prestazione (UPC2)
- Stima multiresiduo della vitamina A e dei suoi derivati nei campioni di sette prodotti cosmetici mediante cromatografia liquida abbinata e rivelazione UV

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