Development of bimetal-organic frameworks-polypyrrole composite as a novel fiber coating for direct immersion solid phase microextraction in-situ supercritical fluid extraction coupled to gas chromatography for simultaneous determination of furfurals in dates

A new, simple, hyphenated technique couples supercritical fluid extraction and direct immersion SPME to GC-FID (SFE–DI-SPME–GC–FID) for the determination of 2-furaldehyde (2-F) and 5-hydroxymethylfurfural (5-HMF) in solid foods. A bimetal-organic...
