Thermodesorption mass spectrometry study of nanooxides systemsPublished by Astacus on Fri, 01/06/2017 - 16:02
Time-of-flight one pass temperature programmed desorption mass spectrometry (TPD MS) as a sensitive method permits to distinguish different types of surface functionalities, and to investigate the influence of adsorption/re-adsorption time on solids, polymers etc. This method helps identify correlations between structure of materials and properties of the interfacial layer.
The TPD MS investigations are carried out in a high vacuum chamber (pressure 10-5 Pa) using a MSC-3 time-of-flight mass spectrometer. Features of the system are fast reaching ultra high vacuum, fresh metal deposition onto chamber walls for experiment cleanliness, small distance between a sample and a detector (0.5 cm) that provides one pass measurement.
Investigations of particles desorption from a surface:
- metals and oxides of metals;
- carbon materials;
- porous and nonporous materials.
