- Аннотация: An approach to the simultaneous determination of five products of the transformation of rocket fuel on the basis of 1,1-dimethylhydrazine (1-methyl-1H-1,2,4-triazole, N-nitrosodimethylamine, N,N-dimethylformamide, and formaldehyde and acetaldehyde dimethylhydrazones) is proposed based on a combination HPLC on porous graphitized carbon (Hypercarb) with mass spectrometry and tandem mass spectrometry detection. The limits of detection are 0.6–7 µg/L. It was found that the stationary phase based on porous graphitized carbon ensures the effective chromatographic retention and separation of nitrogen-containing products 1,1-dimethylhydrazine transformation products by a mixed mechanism, including both hydrophobic and induction interactions with the analytes. The absence of matrix effects in the analysis of natural waters and a methanol extract from peat bog soil was shown.
