Abstract: A measuring apparatus and method for use in measuring diffusible hydrogen concentrations in materials, structures, and other objects. In an embodiment of the invention for use in welding applications, the measuring apparatus (10) includes a sensor assembly (20) that, with an included sealing member (40), defines a sample area (17) on a weld bead (16) from which hydrogen evolves into a sample volume (18) defined by the sealing member (40), a sensor housing (34) and a sensor (22) of the sensor assembly (20). The hydrogen reacts with a sensing layer (28) and a reflector layer (30) positioned on the end of an optical fiber (24), all of which are included in the sensor assembly (20) and are sealably positioned within the sensor (22). The sensing layer (28) comprises a chemochromic material that undergoes changes in physical properties, such as optical transmission properties, when it reacts with hydrogen and these changes are measured by the measuring apparatus (10) to determine the amount of hydrogen evolving from the sample area (17). An optical fiber (46) is joined to the sensor optical fiber (24) to direct light (63) transmitted by a light source (62) in a hydrogen monitoring assembly (60) through the sensing layer (28) to strike the reflector layer (30) which reflects light (67) back through optical fiber (46) to a detector (68) in the hydrogen monitoring assembly (60). A signal analyzer (72) is included in the hydrogen monitoring assembly (60) and is calibrated and configured to measure the diffusible hydrogen concentration in the weld bead (16) based on measured changes in the optical transmission properties of the sensing layer (28).

Abstract: Electromagnetic acoustic resonance method by using EMAT is used for determining hydrogen concentration of radioactive metallic object. In one preferred embodiment, resonance frequencies fr, fr are measured with the EMAT, where where fr is a resonance frequency when a direction of an amplitude of a transverse ultrasonic wave generated by the EMAT is the same as the rolling direction of the metallic object of rolled material, and ft is a resonance frequency when a direction of the amplitude of the transverse ultrasonic wave is perpendicular to the rolling direction. A value R is calculated by using: R=(fr−ft)/{(fr+ft)/2}. The hydrogen concentration of the metallic object is calculated on the basis of the experimentally determined relation between the value R and hydrogen concentration.

Abstract: A portable instrument for automatic collection and analysis of airborne lead concentrations in ambient air environments. Its improvements to the art of airborne lead detection and analysis permit the apparatus to analyze samples previously collected by personal monitors, for example, worn on the clothing of personnel working in contaminated sites. The apparatus also brings to the art of lead analysis a method of contaminant collection that ensures a greater capture efficiency of airborne contaminants, thereby increasing the accuracy of the instrument and its measurement capabilities while providing near real-time analysis and measurement in a portable self-contained battery-powered device. The apparatus also offers a remarkable improvement in the reduction of wastes incurred in the collection and analysis of airborne lead contaminants which is a novel method of concentrating the samples and recycling the analysis media used to concentrate and solubilize lead contaminants.

Abstract: A process and apparatus are disclosed for the detection and measurement of sulfur in both organic and inorganic sulfur-containing compounds. The process includes admixing a sample including a sulfur-containing compound with oxygen, and then exposing the mixture to a source of combustion causing heat in the presence of a combustion supporting reducing agent at a combustion site. The resulting gaseous combustion products are vacuum extracted from the combustion site, and then directed into a darkened low pressure chamber. The combustion products in the low pressure chamber are then contacted with ozone, with the result that the sulfur combustion products are converted to chemiluminescent sulfur dioxide. The emitted chemiluminescence is then detected, and may be measured to provide a quantitative indication of the amount of sulfur in the original sample. The preferred source of oxygen is air, the preferred form of combustion heat is a flame, and the preferred form of reducing agent is hydrogen gas.

Abstract: The present invention describes the process and apparatus for the simultaneous measurement of sulfur-containing compounds and organic compounds with or without sulfur in their structures. A detector cell is described that allows simultaneous measurement of compounds that can be ionized in a flame and thereby cause the electrical conductivity of the flame to increase, and the selective measurement of sulfur-containing compounds which simultaneously form sulfur monoxide. Sulfur monoxide, upon mixing with ozone, emits light from 240 to 450 nm. The intensity of the light can be measured and related to the concentration of sulfur in the sample, while changes in electrical conductivity of the flame measured by imposing a voltage across the cell quantifies the organic compounds irrespective of whether or not they contain sulfur. Ratios of the signals of light intensity and electrical conductivity are different for each compound and, when the detector is coupled with a chromatographic separation column and process, this ratio facilitates the identification of unknown constituents in a mixture.
