Analytical capabilities of a thermodesorption spectrometer with a surface-ionization detection of organic molecules in air

This paper presents the results of research on development a mathematical model thermal desorption spectrometry with surface ionization method for detecting molecules organic substances, as well an analysis capabilities spectrometer operating basis this method. The was developed regularities spectrometry, substances under non-stationary conditions. consists detector and evaporator heated in thermally programmed mode. adjustment selection mode were carried out analytical studied by comparing thermodesorption spectra mixture chromatographically pure cannabinoids extract biological fluids marijuana user (blood, urine), morphine urine extracts heroin user. showed perspectives proposed instrument detection drugs psychotropic biomaterials consumers these without chromatographic separation. Keywords: biosamples drug users, method, spectrum, identification quantitative analysis.
