length of 30 m and film thickness of 0.25 µm. (b) The
initial temperature of the oven was 70°C for 3 min, which
was then increased to 300°C, at a rate of 10 °C/min, and
maintained at 300°C for 20 min. The analytical period for
each cycle was 46 min. (c) The temperatures of the injection
port, ion source, and interface were set at 280°C, 230°C and
290°C, respectively. (d) The carrier gas flow rate was 1.0
mL/min, corresponding to a linear velocity of 36.7 cm/sec.
(e) The injection mode was splitless, with an injection
volume of 1.0 μL. Analysis was conducted in selective ion
monitoring (SIM) modes. The process of the quantification
ion and confirmation ion for the SIM mode were based on
that of Orecchio (2011)
