Abstract

A gas adsorption amount measurement device, which is an example of an embodiment of the present invention, comprises at least one sample tube, a reference tube, and a control unit. The control unit is configured to measure, using adsorption gas, reference volumes Vdst,ads of a free space of the sample tube not having a sample and reference volumes Vdref,ads of a free space of the reference tube, respectively and to calculate a gas adsorption amount of the sample using the reference volumes Vdst,ads, Vdref,ads.

Abstract

This true density measurement device is a device that is used to measure the true density of a sample by a gas phase substitution method, and is provided with: a sample chamber for accommodating the sample, the sample chamber being pressurized through the introduction of an inert gas; and an expansion chamber into which is released the inert gas filling the sample chamber. The expansion chamber under conditions of normal use, is opened and closed by a detachable cover, and the volume thereof is modified by insertion or withdrawal of a volume modification member.

Abstract

This true density measurement device is a device for measuring the true density of a sample by a gas phase substitution method, and is provided with a sample chamber for housing the sample, and a lid for providing closure to an opening of the sample chamber. The lid is a non-rotating lid that is pressed against the rim of the opening to hermetically seal the sample chamber.
