Abstract
This paper describes the application of multivariate analysis (MVA) techniques to terahertz (THz) gas-phase absorption spectra at around 245 GHz. The THz spectra of gaseous volatile organic compounds (VOCs) and their complex mixtures at pressures between 10 and 5000 Pa were acquired with a vector network analyzer (VNA) and an absorption cell. With the subsequent MVA our experiment shows the feasibility of qualitative and quantitative substance identification. Since the tested VOCs are biomarkers and/or can be found on the EPA (US Environmental Protection Agency) list of harmful substances there is a potential for application in medicine and security. In particular because our measurements show that there is no need of measuring in the Doppler limit.
