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
Features and Benefits
- idoneidad probada y especificada para UHPLC-MS y UHPLC-UV: para flexibilidad analítica
- calidad especificada en positivo y negativo en ionización por electropulverización (ESI) positiva y negativa y espectrometría de masas con ionización química a presión atmosférica (APCI-MS) para límites de detección más bajos y confianza en los análisis para todos los modos importantes de MS (prueba 1)
—ESI/APCI (+) < 2 ppb
—ESI/APCI (-) < 10 ppb - menor perfil de impurezas: para líneas base sin interferencias (prueba 2)
- microfiltrado a través de un filtro de 0,2 μm (prueba 3) para proporcionar:
—una vida útil prolongada a los filtros y las partes mecánicas de los sistemas de HPLC
—riesgo reducido de obstrucción de las columnas - envasado en botellas de vidrio de borosilicato para minimizar la contaminación por iones metálicos
- menores niveles de impurezas metálicas traza para una formación mínima de aductos de iones metálicos
—< 5 ppb - el menor nivel de impurezas de polietilenglicol (PEG) en la línea de disolventes UHPLC-MS (cociente señal/ruido 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
