摘要： A chemical indicator device for use in detecting exposure to an oxidizing agent, such as hydrogen peroxide, comprising a substrate or support upon which is disposed a chemical indicator composition (ink) for detecting an oxidizing agent, such as hydrogen peroxide. The chemical indicator composition further comprises an indicator dye that achieves a distinct range of different color changes with clear transitions between colors, upon exposure to different doses of the oxidizing agent, thus allowing for both a qualitative and semi-quantitative assessment of exposure to the agent.

摘要： Provided are a method for preparing a standard sample in which a uniform dispersion of a predetermined concentration of red phosphorus is guaranteed even in a very small amount, and an analytical method for quantitatively determining red phosphorus contained in a resin by pyrolysis-GC/MS, in which the standard sample is used. The method for producing a standard sample for quantitatively determining red phosphorus contained in a resin includes the steps of preparing a red-phosphorus-containing compound by weighing a predetermined amount of red phosphorus and uniformly mixing the red phosphorus in a resin; decreasing the number of particles having a maximum diameter of 5 µm or more to 1/20 or less of the number of particles having a maximum diameter of 1 µm or more and less than 5 µm by pulverizing the red-phosphorus-containing compound; and obtaining a standard sample by weighing about 0.05 to 10 mg, preferably about 0.1 to 0.5 mg of the pulverized red-phosphorus-containing compound. The analytical method is a method for quantitatively determining red phosphorus contained in a resin by pyrolysis-GC/MS, in which the standard sample is used.

摘要： The present invention provides a device useful in the photo-oxidation of a sample liquid and in the measurement of the oxidized carbon content thereof. The device comprises a cell, at least two elongate probes, and a temperature sensitive element. The cell comprises a rigid light-transmissive outer wall that encloses a continuous predetermined internal volume The elongate probes -- providing collectively the ability to measure temperature and conductivity -- penetrate through the rigid outer wall and extend substantially into the cell's internal volume. At least one of the elongate probes is hollow at least partially along its length, the temperature sensitive element being positioned within this bore. A methodology involving the use of the device is also described.

摘要： The present invention relates to an apparatus and method for determining the concentration of nitric oxide (NO) in a gas mixture such as air. The gas sample containing NO is mixed with a gas containing ozone (O 3 ), and the change in the ozone concentration is measured after a sufficient time is allowed for the reaction between NO and O 3 to take place and destroy a measurable quantity of O 3 . In the disclosed embodiment, the concentration of ozone is measured using the technique of UV absorption. In this case, the invention has the advantage over other instruments for measuring NO of having absolute calibration based on the known extinction coefficient for ozone at ultraviolet wavelengths. The invention discloses both static and dynamic flow systems, and the NO concentration measurements may be made over a wide pressure range.

摘要： The invention relates to a device and a method for detecting ammonia, in particular for detecting an NH3 emanation in a catalyst assembly (1). According to the invention, a gas, in particular, an exhaust gas of a lean-driven internal combustion engine, is fed by a first gas-supply device and ammonia is fed by a second gas-supply device to an SCR catalyst (12). A first element, in particular, an oxidation catalyst (10) is provided which first, at least substantially, oxidizes gas components which can be oxidized and which are contained in the gas. In addition, a gas (5'') which emanates from the SCR catalyst (12) is analyzed by a second element, in particular, a gas sensor (15) with regard to the content of components which can be oxidized. The gas sensor (15) detects gas components which can be oxidized preferably in a non-selective manner and is connected via a processing unit (16) and a control unit (17) to a metering system (13) which controls the supply of ammonia.

摘要： The invention provides an ozone hydroxy radical analysis method for a liquid carrying a suspension of organic matter. The analyser comprises a reactor vessel 2 having sample inlets and outlets 3 and 4 respectively for a liquid stream 5. The reactor vessel 2 is connected to a control system 10 and is fed from an acid vessel 15, a base vessel 16 and an ozone generator 20. The reactor vessel 2 contains glass beads and a catalyst is introduced into the reactor vessel. With a manganese catalyst and glass beads, the manganese coats the glass beads which therefore retain catalyst within the reactor vessel.

摘要： Apparatus and method for the measurement of total organic carbon, total inorganic carbon and total carbon of water are described. The sample is acidified (16, 22) and split (142) into an inorganic carbon stream and a total carbon stream (42). The inorganic carbon in the inorganic stream (142) is oxidized and both the organic and inorganic carbon in the total carbon stream is oxidized (30). The resulting carbon dioxide is measured in each stream using carbon dioxide sensors (56, 156) employing a gas permeable membrane (58) dividing deionized water from the oxidized sample water and a pair of micro-conductivity and temperature sensors (94).
