compounds in real-time and delayed modes are optimized. The physicochemical characteristics of the sorption of thiosemicarbazides are determined. The decomposition and fragmentation of their metastable protonated molecules are studied. Schemes are proposed for the formation of fragmented and characteristic thiosemicarbazide ions in different modes of ionization.

Abstract Procedures for qualitative and quantitative analysis of microimpurities of alkylhydrazines and their transformation products in hydrocarbon rocket propellants Naftil, Syntin, and Detsilin by gas and liquid chromatography with on-line and off-line mass-spectrometric detection were developed. Reliable detection of an unsymmetrical dimethylhydrazine impurity in Naftil multicomponent propellant
