Ground wheat and maize grains were extracted with acetonitrile-water-acetic acid (79:20:1, v/v/v), followed by defatting with cyclohexane, and subjected to SBME-LC-FLD analysis. SBME devices were constructed by packing 2 mg sorbent (C18) into porous polypropylene micro-tubes (2.5 cm length, 600 mu m i.d., and 0.2 mu m pore size). SBME devices were conditioned with methanol and placed into 5 mL stirred sample solutions for 70 min. After extraction, OTA was desorbed into 200 mu L of methanol for 15 min, the solution was removed in vacuum, the residue was dissolved in 50 mu L of methanol-water (1:1, v/v) and ochratoxin A content was determined by HPLC-FLD. Under optimized extraction conditions, the limit of detection of 0.9 mu g center dot kg(-1) and 2.5 mu g center dot kg(-1) and the precision of 3.4% and 5.0% over a concentration range of 1 to 100 mu g center dot kg(-1) in wheat and maize flour, respectively, were obtained."],["dc.description.sponsorship","Open-Access-Publikationsfonds 2015"],["dc.identifier.doi","10.3390/toxins7083000"],["dc.identifier.isi","000360202700018"],["dc.identifier.pmid","26251923"],["dc.identifier.purl","https://resolver.sub.uni-goettingen.de/purl?gs-1/12389"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/36390"],["dc.notes.status","zu prüfen"],["dc.notes.submitter","Najko"],["dc.publisher","Mdpi Ag"],["dc.relation.issn","2072-6651"],["dc.rights.access","openAccess"],["dc.title","Determination of Ochratoxin A in Wheat and Maize by Solid Bar Microextraction with Liquid Chromatography and Fluorescence Detection"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.peerReviewed","yes"],["dc.type.status","published"],["dc.type.version","published_version"],["dspace.entity.type","Publication"]]
