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.

Description générale
Application
The product is used as a solvent in studies such as the following:
- high resolution mass spectrometric (HRMS) analysis of per- and polyfluoroalkyl substances (PFAS) in environmental water samples[1]
- UHPLC-MS/MS study of PFAS and/or perfluorooctane sulfonate (PFOS) in sewage sludge[2] and soil samples[3][4]
Caractéristiques et avantages
- suitability tested and specified for UHPLC-MS and UHPLC-UV: for analytical flexibility
- specified quality in positive and negative in positive and negative electrospray ionization (ESI) and atmospheric-pressure chemical ionization-mass spectrometry (APCI-MS) for lowest detection limits and confidence in analyses for all important MS modes (test 1)
—ESI/APCI (-) < 10 ppb
- lowest impurity profile: for interference-free baselines (test 2)
- microfiltered through 0.2 μm filter (test 3) to provide:
—reduced risk of column clogging
- packed in borosilicate glass bottles for minimized metal ion contaminations
- lowest levels of trace metal impurities for a minimum metal ion adduct formation
- lowest level of polyethylene glycol (PEG) impurities in UHPLC-MS solvent lineup (PEG S/N signal-to-noise-ratio < 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
