- Аннотация: The behavior of eight nitrogen-containing toxic products of rocket fuel transformation (formaldehyde dimethylhydrazone, N,N-dimethylformamide, N,N-dimethylguanidine, 1,2,4-triazole, pyridine, imidazole, pyrazine, pyrazole) under conditions of dopant-free atmospheric pressure photoionization was studied. It was found that the analytes under study give intense signals of protonated molecules, while the efficiency of ionization largely depends on temperature, as well as on the solvent composition and flow rate. Based on a combination of atmospheric pressure photoionization with chromatographic separation on porous graphitized carbon, we proposed a new approach to the highly sensitive determination of rocket fuel transformation products. The developed approach is distinguished by minimal matrix interferences and was successfully tested in the analysis of real samples.
