Experimental A Supelco DVB/Carboxen/PDMS StableFlex SPME fiber was placed in an enclosed plastic bag with a banana for 10 minutes during each analysis. For direct analysis of the SPME fiber, the JEOL AccuTOF-DART™ system was set to the following parameters: needle voltage 3500V, discharge electrode 150V, grid electrode 250V, helium temperature 200 degrees C, and helium flowrate 2.3 L/min. A JEOL GC-Mate II high resolution sector bench top system equipped with a DB5-HT (0.25mm × 30m) was used for the GC-MS portion of the analysis. The GC-Mate II was set to the following parameters: inlet temperature 250 degrees C, split ratio 30, and helium flowrate 1.2 mL/min. The GC oven was set for the following temperature profile: 40 degrees C held for 2 min, ramp from 40 to 260 degrees C at 20 degrees C/min, 260 degrees C held for 2 min.
