Surface-assisted laser desorption/ionization mass spectrometry for the detection of low-molecular-weight and oligomeric products of 1,1-dimethylhydrazine transformation on the surfaces of construction materials

Abstract

Surface-assisted laser desorption/ionization mass spectrometry (SALDI) was applied to study the products of 1,1-dimethylhydrazine transformation on the surfaces of construction materials. The approach proposed makes it possible to distinguish the transformation products of 1,1-dimethylhydrazine from the low-molecular-weight compounds and oligomers utilized in the production of construction materials, which undergo different transformations in the course of operational processes.
