“…As a reminder, each test was carried out with a commercial red wine sample spiked with a standard solution of (2 E ,4 E ,6 Z )-nonatrienal and trans -4,5-epoxy-( E )-2-decenal at 1 μg/L. Based on literature data on the extraction of volatile compounds from wine, three different cartridges combined with three different solvents were tested. − The cartridges tested were as follows: Oasis HLB (reverse phase, 60 mg, 30 μm, Waters), Supelclean LC-18 (reverse phase, 500 mg, 45 μm, Supelco), and Chromabond HR-X (normal phase, 200 mg, 85 μm, Grosseron). For solvent systems, we tested dichloromethane, dichloromethane/pentane (50:50, v/v), and dichloromethane/methanol (90:10, v/v).…”
