Helium Porosimetry: Principles, Applications, and Equipment
Helium porosimetry involves a process for
measuring the void size range within
materials . Founded on Bernoulli's
law , it
measures the capacity of the gas that
penetrates the cavities at multiple pressures. The
equipment typically
includes a material holder, a inert gas
supply , a
Gas pycnometer pressure transducer, and a heat control system. Implementations are
widespread in
industries such as composites , catalytic support,
filtration media, and
battery materials.
