Porosimetry
The Micromeritics Autopore IV 9500 has one high-pressure port and two low-pressure ports. Due to the use of elemental mercury, only the MSE technician operates the instrument. Data is collected and analyzed via a windows XP environment. Samples should be dried in a 50C-drying oven 24 hours before the measurement is made. Please give 24 hours notice before scheduling an appointment. Please use the link provided for more technical information.
