Eutectic Gallium‐Indium as a Potential Non‐Toxic Replacement in Mercury Intrusion Porosimetry
Advanced Materials Technologies, EarlyView.A practical alternative to mercury intrusion porosimetry is presented using non‐oxidized eutectic gallium‐indium. An eGaIn Filling Station enables oxygen‐free preparation of standard penetrometers, and the resulting measurements faithfully reproduce pore‐size distributions and intrusion volumes measured with mercury across several standard reference ...
