Thermal desorption spectroscopy (TDS) is a technique used to investigate hydrogen embrittlement and hydrogen-induced failure in materials like steel. It uses controlled heating to determine the amount of diffusible hydrogen emitted from the material. When compared to other techniques, TDS stands out for its excellent sensitivity and capacity to quantify minute amounts of desorbed hydrogen.

Introduction to Thermal Desorption Spectroscopy (TDS)
Thermal desorption spectroscopy (TDS), also known as TPD (Temperature-programmed desorption), plays a crucial role in catalysis applications. It is a technique for monitoring surface interactions between molecular species as the surface temperature changes in a controlled environment. Thermal Desorption Spectroscopy, widely used in catalysis, aids scientists in comprehending the intricate workings of catalytic processes such as adsorption, surface reaction, and desorption.
Principle and Methodology of TDS
Temperature-programmed desorption is a method used to determine the strength of interactions between a surface and adsorbed species. It involves placing a catalyst in a reactor and pushing an inert gas into the chamber or a sample in a UHV chamber without carrier gas. The sample is dosed with probe gas, and the desorption products are analyzed using a mass spectrometer.

Instrumentation
The instrumentation typically includes a TDS vacuum system for avoiding contamination, a heating system for the controlled heating of the sample, a mass spectrometer for the detection and quantification of desorbed species, and a data acquisition system with software for recording and analysis of desorption spectra. There can be more elements in the present TDS systems, such as quadrupole mass filters, electron impact ionization sources, and cryogenic cooling stages that provide significantly better sensitivity and accuracy.
Applications of Thermal Desorption Spectroscopy
TPD is a surface chemistry method used in various applications such as hydrogen in metals, photovoltaics, semiconductors, and thin films. It provides scientists with vast information and helps identify contaminants or performance problems in production chains, ensuring clean and high-quality processes. Applications include materials characterization, nanotechnology, photovoltaics, semiconductors, surface science, and thin films.
