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
- Testato e specificato adeguatamente per UHPLC-MS e UHPLC-UV: per flessibilità analitica
- qualità specificata per la ionizzazione electrospray (ESI) positiva e negativa e per la spettrometria di massa con ionizzazione chimica a pressione atmosferica (APCI-MS) per limiti di rivelazione e intervalli di confidenza ridotti al minimo nelle analisi con i metodi MS principali (test 1)
—ESI/APCI (+) < 2 ppb
—ESI/APCI (-) < 10 ppb - profilo di impurezze minimale: per linee di base prive di interferenze (test 2)
- Microfiltrato con filtro da 0,2 μm (test 3) per assicurare
—una lunga durata di esercizio ai filtri e alle parti meccaniche dei sistemi HPLC
—rischio di intasamento della colonna ridotto - confezionato in bottiglie di vetro borosilicato per contaminazioni da ioni metallici ridotte al minimo
- livelli minimi di impurezze metalliche in tracce, per ridurre al minimo la formazione di addotti di ioni metallici
—<5 ppb - i livelli di impurezze di glicole polietilenico (PEG) più bassi tra tutti i solventi per UHPLC-MS (PEG S/N rapporto segnale/rumore < 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
