Paper Abstract

The paper presents our progress in using a THz -TDS system for spectral characterization of some organic substances. We try to develop a data base for substances from different domain that include in their category materials having a common characteristic: they are dangerous or they are even forbidden in their category of utilization. We have developed procedures for measuring the absorption spectra in quasi same conditions for all substances. Like this we have record absorption spectra for: food additives (azoic-dyes and fragrance), pesticides (insecticides, fungicides, herbicides) and some alcoholic polar substances (methanol, ethanol) etc. We have demonstrated that our measurements technology can be used not only for recording the spectra of the organic samples, but we can discriminate between different levels of concentration of the substances or even we detect the forbidden substances in an organic material.
