The only manual handling was transferring the sample (tea, oil, seed, nibbles, softdrinks, chocolate) and reagents (NaOH, Na 2 CO 3, internal standard) in the headspace vial. The sample was hydrolysed for 5 min at 90 °C in the agitator of the autosampler. Next, the fiber was exposed to the headspace in the vial for 25 min.
Sample preparation: A 500 µL aliquot of oil sample solution (10 mg/mL in tetrahydrofuran), was mixed with 1000 µL of Hantzsch reagent in a 1.5 mL centrifuge tube. The solution was heated at 75 °C for 1 hour. Samples were centrifuged (10,000 g for 3 mins), and the supernatant was transferred to an HPLC vial.
