摘要： An online monitor for trace sodium in high-purity water, and an online monitoring method and device thereof are provided. Under the control of an embedded industrial computer, an injection-calibration system conveys calibrated water samples and to-be-measured water samples to a flame atomization system continuously and stably. The flame atomization system forms a negative pressure field using a high-purity hydrogen-oxygen mixture as carrier gas, draws in the to-be-measured water samples for atomization, mixing and droplet separation, and then ignites a characteristic spectrum which emits sodium at a high-temperature inner cone. A photoelectric sensor system quickly scans the characteristic spectrum of sodium, and outputs a second-order differential modulation sodium spectrum after removing background interferences. A data acquisition system acquires an analog signal of the second-order differential modulation sodium spectrum, converts the analog signal into a digital signal and outputs the digital signal to the embedded industrial computer for real-time monitoring and control.

摘要： In a gas analysis apparatus including analyzers that need ignition, such as FIDs, in order to make it possible to surely ignite the analyzers while downsizing the entire apparatus, the apparatus includes first and second analyzers to accept a sample gas, a first gas line provided with the first analyzer, a second gas line provided with the second analyzer and joined downstream of the first analyzer in the first gas line. At least one of the first analyzer and the second analyzer is configured to cause pressure fluctuations in the gas line including the analyzer when analyzing the sample gas. A first backflow prevention mechanism is disposed between another of the analyzers and a junction of the gas lines. The first backflow prevention mechanism is configured to prevent a fluid from flowing backward from the one of the analyzers through the junction toward the another of the analyzers.

摘要： Provided is an online detection method of gaseous alkali metal concentration in boiler burning flame. The method includes selecting the user characteristic spectral line to be measured; based on the characteristic spectral line of the alkali metal, constructing a fitting model between radiation strength of the characteristic spectral line of the alkali metal in the burning flame and the gaseous alkali metal concentration and flame temperature; calibrating the spectrograph under absolute radiation strength; measuring a flame object corresponding to an alkali metal concentration by the calibrated spectrograph to obtain the radiation strength and flame temperature of the characteristic spectral line of the alkali metal. The detection method can detect the concentration of the gaseous alkali metal in the burning flame of the detection furnace quickly and accurately as well as detect the content of the base metals, involves simple devices, low cost, and is suitable for field measurement.

摘要： A method of detecting defects in membranes such as ion exchange membranes of electrochemical cells. The electrochemical cell includes an assembly having an anode side and a cathode side with the ion exchange membrane in between. In a configuration step a chemochromic sensor is placed above the cathode and flow isolation hardware lateral to the ion exchange membrane which prevents a flow of hydrogen (H2) between the cathode and anode side. The anode side is exposed to a first reactant fluid including hydrogen. The chemochromic sensor is examined after the exposing for a color change. A color change evidences the ion exchange membrane has at least one defect that permits H2 transmission therethrough.

摘要： A method and a particle sensor for measuring particles, especially soot particles, in which the particles to be detected accumulate in a measuring region of the particle sensor. The particles located in the gas stream or the particles already accumulated in the measuring region are burned by a combustion device, the combustion being controlled via a control signal from a control unit, which is electrically connected to a measuring device, in such a way that the quantity of the particles adhering in the measuring region remains constant. The physical variable of the combustion device, which leads to the controlled combustion of the particles, is drawn upon as the signal amplitude of the particle sensor.

摘要： A method for influencing and monitoring the oxide layer on metallic components of hot CO2/H2O cycle systems, in particular of CO2/H2O gas turbine installations, in which a hydrocarbon-containing fuel is burnt with oxygen, and the excess CO2 and H2O formed is removed from the cycle system at a suitable location. To protect the oxide layer of the components which are under thermal load, an excess of oxygen is used, the level of which is dependent on the current state of the oxide layer, the state of the oxide layer being determined by periodic and/or continuous measurements.
