网页The vials were sealed by crimp-top caps with TFE-silicone headspace septa. At the time of SPME analysis, each vial was placed in 100 ° C for 5 min. And 120 μm divinylbenzene (DVB)/carboxen (CAR)/polydimethylsiloxane (PDMS) extraction fiber was exposed to the headspace of the sample for 15 min at 100 ° C.

网页2014年5月23日 · In headspace analysis, we found that the phenol equilibrium in the system can be achieved in 20 min at 150 C, much lower than that of phenol's b.p. (181.7 C), as shown in Fig. 7. Therefore, the batch phenol analysis in the present method was first performed at 130 °C for 6 h in laboratory oven and then transferred to HS-GC for
