摘要： The invention relates to a process for determining the total oxygen content and the total carbon content in ammonia, in which ammonia is first split into nitrogen and hydrogen, then the oxygen still present in the ammonia is reacted essentially fully with hydrogen to give water and the carbon still present is reacted essentially fully with hydrogen to give methane. In a next step, the water content and the methane content in the gas are determined. Finally, the total oxygen content is determined from the water content and the total carbon content from the methane content. The invention further relates to an apparatus for performing the process, which comprises a cracker for splitting the ammonia and for converting the oxygen- and/or carbon-comprising compounds, and at least one cavity ring-down spectrometer for detecting the water content and/or carbon content. The cracker and the at least one spectrometer, and also all devices and connecting lines between the cracker and the spectrometer, are surrounded by an inert gas.

摘要： The invention relates to a method for determining the total oxygen content and the total carbon content in ammonia, wherein ammonia is firstly cleaved into nitrogen and hydrogen, then the oxygen still contained in the ammonia reacted with hydrogen to give water and the carbon still contained in the ammonia reacted with hydrogen to give methane, essentially to completion. In a subsequent step, the water content and the methane content of the gas are determined. Finally the determinations of the total oxygen content from the water content and the total carbon content from the methane content are carried out. The invention further relates to a device for carrying out the methods, comprising a cracker for cleaving the ammonia and for reacting the compounds containing oxygen and/or carbon and at least one cavity ring-down spectrometer for recording the water content and/or carbon content. The cracker and the at least one spectrometer and all devices and connector lines between the cracker and the spectrometer are blanketed in an inert gas.

摘要： In various embodiments, rapid, sensitive detection of molecular hydrogen is achieved by in a detector that divides sample gas into two flows by dividing the sample gas before dampening variation and converting hydrogen to water vapor at two different points. For example, a detector may receive sample gas that includes ambient water vapor and hydrogen, divide the sample gas into a chemical conversion flow and bypass flow, perform a first chemical conversion of hydrogen in the chemical conversion flow to water vapor, alternate between drying the converted chemical conversion flow or the bypass flow to produce a modulated flow, perform a second chemical conversion of hydrogen in the modulated flow to water vapor, measure water vapor in the converted modulated flow to produce a water vapor signal, separate the water vapor signal in the time domain to extract a hydrogen-derived water vapor signal, and output a hydrogen signal based thereon.

摘要： A system and method is provided that facilitates the uniform development of a pattern on a photoresist material layer using a developer. The present invention accomplishes this end by considering the acid-base relationship of the photoresist material and developer and monitoring the development of water formed in the development process. Typically, photoresist material is purchased or manufactured with known concentrations of resin and photoacid generator. Therefore, by monitoring the development of water in the development process, the present invention can measure the acid consumption in the development process. The present invention can then utilize this information in optimizing the developer volume, developer concentration and developer time to improve the quality of the developed image pattern on the photoresist material layer.
