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.

General description
Application
Relatado para uso em investigações LC–MS/MS de:
- Plasma sanguíneo e amostras de soro fracionadas em vários
- peptídeos de absorventes de cromatografia em amostras biológicas animais
Features and Benefits
- Adequação testada e especificada para UHPLC-MS e UHPLC-UV: Para flexibilidade analítica, a
- qualidade especificada é positiva e negativa em ionização por eletropulverização positiva e negativa (ESI) e espectrometria de massa por ionização química à pressão atmosférica (APCI-MS) para os limites de detecção mais baixos e confiança nas análises para todos os modos MS importantes (teste 1)
—ESI/APCI (-) < 10 ppb
- perfil de impureza mais baixo: para linhas de base sem interferência (teste 2)
- microfiltradas através de filtro de 0,2 μm (teste 3) para proporcionar:
—risco reduzido de obstrução da coluna
- embalados em frascos de vidro de borossilicato para minimizar contaminações de íons metálicos
- níveis mais baixos de impurezas de metais residuais para uma formação mínima de aduto
- de impurezas de polietilenoglicol (PEG) na linha de solventes UHPLC-MS (relação sinal/ruído PEG S/N < 50)

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