SALDI Mass - spectrometry for research clusters as a part of poorly conducting deposits
Keywords:
clusters, MALDI/SALDI mass-spectrometry, poorly conducting deposits, surface chemistry.
Abstract
The method of Surface Assisted Laser Desorption/Ionization mass spectrometry is used to study
chemistry of poorly conducting deposits forming channels’ walls of the combustion chamber cooling path of
the liquid fuel rocket motor. Such deposits interfere with the operations temperature conditions of the
product, making difficult heat exchange. This method simplifies sample preparation and allows to obtain
deposits qualitative composition and the nature of metal clusters formed under "soft ionization" dates.
