The PCT-XAS-B01 is developed for laboratory benchtop XAFS systems and is also compatible with laboratory X-rayabsorption spectrometers and compact XAS platforms, enabling in situ structural characterization during plasma reactions.The system integrates plasma discharge, gas control and temperature regulation, allowing studies of local catalyst structure and electronic-state changes under non-synchrotron conditions. A modular design supports transmission, fluorescence and hybrid detection modes without changing the reaction cell structure for different measurement configurations. It is ideal for catalyst screening, mechanistic research, teaching platforms and routine in situ experiments, markedly reducing dependence on synchrotron beamtime and improving the efficiency of in situ XAS research.

• Benchtop compatibility: designed for laboratory-grade XAS and compact XAS platforms.
• Multi-mode detection: supports transmission, fluorescence and hybrid detection without changing the cell body.
• Efficient screening: enables routine in situ tests and rapid catalyst screening, reducing synchrotron beamtime dependence.
