^aThe repeatability expressed as RSD of the area ratios for all the identified volatile compounds in five identical samples (spiked at 10μgL⁻¹)

^bThe reproducibility expressed as RSD of the area ratios for all the identified volatile compounds in one sample (spiked at 10μgL⁻¹) over 2-week period

^cRecovery rate is calculated based on two standard addition levels, namely low and high
