Title:
水素透過検出用試料ホルダー及び水素透過拡散経路観測装置
Document Type and Number:
Japanese Patent JP7407483
Kind Code:
B2
Abstract:
The sample holder 30 comprises: a holder body 31 for holding the sample 17; an electrolyte introduction chamber 31b provided with an opening 31c that opens to a measurement region 17a of the sample; a retainer plate 33, which is provided with a through-hole 33a corresponding to the measurement region of the sample, for retaining the sample from the electron source side around the through-hole to sandwich the sample airtightly with the holder body; double sealing members 32 arranged between the surface of the holder body and the sample so as to surround the periphery of the measurement region of the sample; a differential exhaust pipe 35, which opens to a space between the sealing members on the surface of the holder body, for exhaust the space through the opening; and electrodes 19 for electrolysis made up of a bias application electrode 19a and an opposing electrode 36.
