Choose from a round or flat base with a beveled or square edge finish. Round base vials are compatible with most autosamplers and more easily handled by robotic arms that lift the vial from the tray. Flat base vials maximize heating efficiency in manual headspace sampling and are required for use in some instrument models.

Besides, GC–MS was used to randomly measure 3 pork samples to confirm the fatty acids. A 0.5 μL aliquot of the sample obtained from pre-processing was injected with a flow of 1.0 mL/min of nitrogen as the carrier gas. The temperatures of the injection and detector were 250 and 300 °C, respectively.

Two grams of root or shoot sample was placed in 100-mL conical flask. After addition of 40 mL acetonitrile with small amount of anhydrous sodium sulfate, it was extracted for 40 min in an ultrasound cleaner. Then the extracted solution was filtered into a 250-mL flat bottom flask, and the sample extracted once again with 20 mL acetonitrile.
