In-Situ Analysis of Essential Fragrant Oils Using a Portable Mass Spectrometer
Figure 5
Electron impact ionization mass spectrum for essential fragrant oils analyzed using a direct membrane probe coupled to portable mass spectrometer. (a) banana, (b) tangerine, (c) papaya, and (d) blueberry muffin. Approx. 5 μL of each was deposited in the flask and left for 2 hours forming a headspace vapor and analyzed for 2 minutes with 70 eV EI energy.
