In-Situ Analysis of Essential Fragrant Oils Using a Portable Mass Spectrometer

Figure 1

Experimental setup used in the detection of different fragrance formulations using a portable quadrupole mass spectrometer coupled with the a direct membrane (DIM) probe; (a) shows the mass spectra obtained for ambient air background without any sample in the flask and (b) the schematic of the portable mass spectrometer coupled to a DIM probe with a flask placed in front of the probe.
