Terpenes Analysis of Essential Oils Using GC-VUV: An Automated, Speed-Based Approach
Terpenes contribute greatly to our senses of smell and taste and thus are integral to flavor and fragrance industries. Current terpenes analysis is performed by GC-FID and GC-MS. However, since many terpenes of interest are isomers, adequate separation is required for accurate identification and quantification, leading to relatively long run times. Vacuum Ultraviolet (VUV) spectroscopy can spectrally distinguish isomers and deconvolve coeluting peaks, which promotes qualitative and quantitative accuracy and allows for significant chromatographic compression. Here we compare the chromatographic compression capabilities of GC-MS and GC-VUV for essential oils analysis, as well as an automated quantitative method for compositional determination.
