SALDI Mass - spectrometry for research clusters as a part of poorly conducting deposits
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.
