With regard to injection time, it
changed from 0.02 to 0.20 min at intervals of 0.02 min, and Fig. 1B
displayed that appropriate response was obtained at 0.10 min. As
was shown in Fig. 1C, equilibration time was assessed by setting up
different time periods (5–50 min, at an interval of 5 min), and
response of acetaldehyde did not vary significantly when
incubating time was more than 35 min.
