Thermal desorption spectrometry – TDS

Thermal desorption spectroscopy (TDS), also known as temperature programmed desorption (TPD) is the method of observing desorbed molecules from a surface when the surface temperature is increased. When molecules or atoms come in contact with a surface, they adsorb onto it, minimizing their energy by forming a bond with the surface. The binding energy varies with the combination of the adsorbate and surface. If the surface is heated, at one point, the energy transferred to the adsorbed species will cause it to desorb. The temperature at which this happens is known as the desorption temperature.

● Thin films
● Photovoltaics
● Hydrogen in metals

Time-of-Flight Secondary Ion Mass Spectrometry – ToF-SIMS

TOFSIMS (Time-of-Flight Secondary Ion Mass Spectrometry) is a powerful surface analysis technique that can provide high-resolution, high-sensitivity chemical composition analysis and imaging of solid surfaces. By using laser or ion beam irradiation on the sample surface, TOFSIMS generates a large amount of secondary ions that are collected and analyzed by mass spectrometry. This allows researchers to determine the chemical composition, structure, and distribution on the sample surface with high precision and accuracy, even at sub-micron spatial resolution. TOFSIMS is widely used in materials science, biomedical research, nanotechnology, and other fields to analyze compound distribution, surface chemical reactions, cell component analysis, and more. Its high resolution and sensitivity make it an invaluable tool for understanding the properties of surfaces and interfaces, including multi-layered structures and depth profiles. Overall, TOFSIMS is a critical analytical tool that has greatly contributed to the advancement of surface science and technology.
