Title:
GAS SORPTION TESTER FOR RAPID SCREENING OF MULTIPLE SAMPLES
Document Type and Number:
Japanese Patent JP2009075105
Kind Code:
A
Abstract:

To provide a device which simultaneously determines gas sorption properties of a large number of material samples.

This device includes a switchable manifold of low-volume conduits and an array of sensors, where each low-volume conduit fluidly couples a single sample of gas sorbing material to a dedicated detector. The switchable manifold is also configured to fluidly couple the samples to a vacuum source or a dosing gas source. Because of a very low internal volume of the conduits, essentially all gas released from a particular sample is detected accurately by a corresponding detector, either through sorption of the released gas, by measuring pressure, or by other means. In this way, a very accurate measurement of the quantity of gas released by the sample is made. In one embodiment, the array of sensor includes hydride-based sensors, which contain a material that forms an optically and/or electrically responsive hydride upon exposure to hydrogen-containing gas.
