Abstract: Methods, processes and compositions are provided for a visual or chemochromic hydrogen-detector with variable or tunable reversible color change. The working temperature range for the hydrogen detector is from minus 100° C. to plus 500° C. A hydrogen-sensitive pigment, including, but not limited to, oxides, hydroxides and polyoxo-compounds of tungsten, molybdenum, vanadium, chromium and combinations thereof, is combined with nano-sized metal activator particles and preferably, coated on a porous or woven substrate. In the presence of hydrogen, the composition rapidly changes its color from white or light-gray or light-tan to dark gray, navy-blue or black depending on the exposure time and hydrogen concentration in the medium. After hydrogen exposure ceases, the original color of the hydrogen-sensitive pigment is restored, and the visual hydrogen detector can be used repeatedly. By changing the composition of the hydrogen-sensitive pigment, the time required for its complete regeneration is varied from a few seconds to several days.

Abstract: An optically-responsive multilayer reflective article is formed by applying a dilute solution or suspension of metallic nanoparticles to an optically-responsive detection layer. The solution or suspension is allowed to dry to form a semicontinuous liquid- or vapor-permeable light-reflective layer that will permit a liquid or vapor analyte to pass through the light-reflective layer to cause an optically-responsive change in the detection layer in the presence of the analyte.

Abstract: An optical gas concentration sensor and method for measuring blood gas based on the light adsorption sensing technique are disclosed. The optical gas concentration sensor comprises a light source, a photo detector, and a gas filtering membrane for separating the indicator and a liquid. A gas in the liquid diffuses to the indicator through the gas filtering membrane so as to change the color of the indicator due to the chemical reaction occurred between the indicator and the gas. Then, the photo detector receives the light passing though the reacted indicator from the light source. The gas concentration is determined based on pH-sensitive absorbance spectrum of the indicator.

Abstract: A hand-held device detects the presence of a preselected substance in the breath. A deformable housing forms a test chamber for interacting an indicator reagent with the breath. An ampoule positioned inside the housing is ruptured by manual pressure through the walls of the housing. The contents of the ruptured ampoule are exposed to the breath introduced into the chamber. The presence of a substance in the breath causes the indicator reagent to undergo a visually ascertainable change. The ampoule is secured within the housing by a pair of filter plugs having inboard concavities to receive the rounded ends of the ampoule to center it within the housing, and plural detents prevent slippage of the filters. Additional embodiments lower the user's risk of being cut by glass shards, prevent reagent inhalation, enhance the visual aspects of the device, and physically indicate the presence of breath flowing through the device.

Abstract: A luminometer for determining the composition of a specimen sample includes an annular guide path for sample containing cuvettes within a light tight housing. A rotor moves spaced segments through the guide path with the cuvettes positioned between the segments. The luminometer further includes one or two detector assemblies coupled to the housing and positioned to view and detect light emitted by cuvettes as they pass along the guide path between segments. A cuvette is advanced around the housing via the rotor and rotor segments and when the cuvette reaches a predetermined position on the housing, a reagent, such as a base, is added to the cuvette to initiate a chemiluminescent reaction within the cuvette and provide an emission of light energy in a predetermined spectral range. The luminometer has a waste aspiration probe to remove the contents of the cuvette after it passes the detector. A cuvette elevator moves a sample containing cuvette into the guide path between segments and an exit chute removes cuvettes after their contents have been aspirated. The luminometer permits continuous uninterrupted sample testing when coupled to an incubation chamber in which the cuvettes receive samples and test specific reagents before they are moved into the luminometer by the elevator.
