The carrier gas was N2 at a flow rate of 1.2 mL/min. The
sample, adsorbed onto an SPME fiber, was introduced into the injection
port and thermally desorbed for 5 min at 210 °C onto a column. The injection
port was equipped with a 0.75 mm i.d. inlet liner to optimize
SPME desorption and sample delivery onto the column.
