Use of the Quantachrome Pycnometer to measure density of particulate materials. The instrument accepts a small sample (5 grams to 50 grams) of material to be analyzed. The sample cell and a reference cell are alternately pressurized to approximately 17 psi with dry gas so that a volume measurement can then be calculated. The instrument will be connected to building nitrogen or helium, and pressure protected with a pressure relief valve/regulator to 25 pounds per square inch. The pycnometer will be used to measure the volume of radiologically contaminated powders. The pycnometer will be located inside of a certified radiological fume hood.
