Description

Descripción general

This Certified Reference Material (CRM) is produced and certified in accordance with ISO 17034 and ISO/IEC 17025. All information regarding the use of this CRM can be found on the certificate of analysis.

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.

Aplicación

The CRM can also be used as follows:

• 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
