摘要： A system for displaying luminescence comprises a crystalline structure comprising a compound having the formula:.alpha.-CuAlX.sub.4wherein the compound has lattice parameters a=b ranging from 5.430(1) .ANG. to 5.751(3) .ANG.; c ranging from 10.069(1) .ANG. to 10.570(4) .ANG.; and X is selected from the group consisting of chlorine, bromine, and a mixture thereof. The crystalline structure may also include a compound of the formula:.beta.-CUAlCl.sub.4wherein the compound has lattice parameters a=7.635(2) .ANG., b=12.842(2) .ANG., and c=6.127(1) .ANG.. The system also includes an excitation source which transmits energy to the crystalline structure such that the crystalline structure displays luminescence. The crystalline structure is also useful in a gas sensor application since the luminescence of the crystalline structure is capable of being quenched in the presence of gaseous material.

摘要： An apparatus and method for visually and continuously monitoring gaseous concentrations of electrophiles such as carbon dioxide. A coating composition comprising an organic binder, filler/pigment, an activator, and carbon dioxide sensitive color indicator interacts with a primed substrate to which it is applied for support. The coated primed substrate may then be used for estimation of carbon dioxide concentration by the detection of a substantially instantaneous and reversible color change of the coated primed substrate.

摘要： The present invention provides a method and apparatus for rapid measurement of a fluid bulk analyte, requiring only microscale volumes. Several fluid bulk analytes can be measured simultaneously and, for biological samples, the cell content can also be measured simultaneously. The invention comprises reporter beads for chemical analysis of fluid bulk properties such as pH, oxygen saturation and ion content. Each reporter bead comprises a substrate bead having a plurality of at least one type of fluorescent reporter molecules immobilized thereon. The fluorescent properties of the reporter bead are sensitive to a corresponding analyte. Reporter beads are added to a fluid sample and the analyte concentration is determined by measuring fluorescence of individual beads, for example in a flow cytometer. Alternatively, reporter molecules which change absorbance as a function of analyte concentration can be employed.

One of the layers is a detection layer (16) in the form of a sheet comprising a reagent to generate a signal by a reaction initiated by the analyte. The other layer (18) is a spreading layer permeable by the analyte position such that analyte entering the container spreads within the spreading layer. The device can be used, for example, as a gas monitor for indicating exposure to hazardous gases or vapours.
