267 Quantification of Limonene from Essential Oil Emissions using Thermal Desorption GC-MS Analysis
This application note demonstrates a method for sampling and analyzing volatile organic compound (VOC) emissions of essential oils using thermal desorption (TD) GC-MS. As part of this work, VOC emissions from three different types of grapefruit essential oil were examined. Limonene, which is known to be the primary VOC emitted from grapefruit and other citrus plants, was directly quantified from emissions of in-home diffusers. For this work, limonene concentrations as high as 27 ppbv were found near the outlet of the diffuser. TD-GC-MS analysis was supplemented with headspace sampling GC-MS to further probe essential oil chemical composition. The results provide greater context into the ways in which consumer products influence indoor air quality and human health.
