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.

Descrizione generale
Ochratoxin A, a mycotoxin, is a naturally occurring secondary metabolite, produced by filamentous fungi, such as Aspergillus and Penicillium. It has been classified as a group 2B substance by International Agency for Research on Cancer, for possibly being carcinogenic to humans.
Applicazioni
- Identification and determination of ochratoxin A in different types of commercial coffee samples using dispersive liquid-liquid microextraction-solidification of a floating organic drop (DLLME-SFO) for sample treatment and ultra high-performance liquid chromatography-positive electrospray ionization-tandem mass spectrometry (UHPLC-(+-ESI)-MS/MS)
- Determination of ochratoxin A in beer samples by a selective method based on salting-out assisted liquid-liquid extraction (SALLE) and ultra high-performance liquid chromatography-tandem mass spectrometry (UHPLC-MS/MS)
- Simultaneous determination of ochratoxin A and ochratoxin B in Tokaj wine samples using online solid phase extraction (SPE) combined with high-performance liquid chromatography-fluorescence detection(HPLC-FD)
- Development of an online-SPE-HPLC method to determine ochratoxin A in wine samples
- Electrochemical determination of ochratoxin A using an aptamer-based on functionalized graphene (f-graphene) doped chitosan in grape juice samples by differential pulse voltammetry

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