AB  - Prompt gamma activation analysis (PGAA) has been further developed to analyze 
      reacting components inside a chemical reactor. The new method, in situ PGAA, was 
      used to determine the hydrogen-to-palladium molar ratio under various conditions 
      of palladium-catalyzed alkyne hydrogenation. The H/Pd molar ratio was 
      successfully measured in the range of 0.1-1.0 in an approximately 2-g catalytic 
      reactor containing a few milligrams of palladium catalyst. The amount of hydrogen 
      was only a few tens of micrograms, and the detection limit was approximately 5 
      microg, i.e., at ppm level compared to the whole reactor. The description of the 
      device, methodological developments, a feasibility study, and results of a series 
      of catalytic measurements are presented.
