3 results about "Hydrogen measurement" patented technology

The invention relates to the fields of materials science and measurement technology and concerns calibration objects, such as those that can be used in analytical spectroscopy. The object of the present invention is therefore to produce electrically conductive calibration blocks, in particular for the calibration of hydrogen measuring instruments. The calibration blocks can be provided in large quantities, simply and cost-effectively. The problem is solved by calibration bodies, in particular for the calibration of hydrogen measuring instruments, consisting at least of an electrically conductive, porous sintered body with a substantially homogeneous distribution of pores and / or defects, such as dislocations, stacking faults and / or twins, in the sintered body, in which an adjustable hydrogen concentration is present depending on the number and size of the pores and / or defects in the sintered body, wherein the hydrogen is physically and / or chemically bound in and / or on the surface of the pores and / or defects, and wherein the set hydrogen concentration in the calibration body decreases in a specified amount over time.

The invention refers to the fields of materials science and metrology and relates to calibration bodies as usable in analytical spectroscopy, for example. The problem addressed by the present invention is therefore that of producing electrically conductive calibration bodies, in particular for calibration of hydrogen measurement devices. The calibration bodies can be provided in large numbers, easily and inexpensively. The problem is solved by calibration bodies, in particular for calibration of hydrogen measurement devices, at least consisting of an electrically conductive porous sintered body, with an essentially homogeneous distribution of pores and / or defect sites, for example dislocations, stacking defects and / or twinned structures, in the sintered body, in which an adjustable hydrogen concentration is present depending on the number and size of the pores and / or defect sites in the sintered body, wherein the hydrogen is in physically and / or chemically bonded form in and / or at the surface of the pores and / or defect sites, and wherein the set hydrogen concentration in the calibration body decreases in the amount specified in each case over time.
