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
Auch der Einsatz als Komponente von Extraktionsmischung beim Untersuchen auf Drogenkonsum in Urinproben mittels GC-MS wurde berichtet.
Features and Benefits
- Für UHPLC-MS und UHPLC-UV eignungsgeprüft und spezifiziert: für analytische Flexibilität
- spezifizierte Qualität bei positiver und negativer Elektrospray-Ionisation (ESI) und chemischer Ionisation bei Atmosphärendruck-Massenspektrometrie (APCI-MS) für geringste Nachweisgrenzen und Vertrauen in Analysen mit allen wichtigen MS-Modi (Test 1)
—ESI/APCI (-) < 10 ppb
- geringstes Verunreinigungsprofil: für interferenzfreie Basislinien (Test 2)
- Durch einen 0,2-μm-Filter filtriert (Test 3), um Folgendes bereitzustellen:
—Verringertes Risiko einer Säulenverstopfung
- In Borosilikatglasflaschen verpackt, um die Kontamination mit Metallionen zu minimieren
- geringstes Maß an Spurenmetallverunreinigungen, um die Metallionenadduktbildung zu minimieren
- geringstes Maß an Polyethylenglycol(PEG)-Verunreinigungen im UHPLC-MS-Lösungsmittelangebot (PEG S/N Signal-Rausch-Verhältnis < 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
