摘要： A method is suggested for determining an absolute gas concentration. The method employs a gas sensor arrangement comprising a gas sensor (1) and means (11, 12) for decomposing a gas to be measured. Furthermore, the method comprises the steps of acquiring a first sensor signal and determining from the first sensor signal at least one initial data point. Then the gas to be measured is decomposed using the means (11, 12) for decomposing the gas of the gas sensor arrangement. A second sensor signal is acquired and from the second sensor signal at least one decay data point is determined. Finally, an absolute gas concentration is determined from a gas concentration function by evaluating the gas concentration function at least for the initial data point and the decay data point.

摘要： An ozonesonde for in-situ measurement of stratospheric ozone concentration profiles by balloon launches includes a hydrothermal buffer having a vessel surrounding a measurement cell having an aqueous reaction solution. The aqueous reaction solution has melting and boiling points dependent on a salt content. A pump is configured to pass ambient air through the aqueous reaction solution. The vessel of the hydrothermal buffer is fillable with water to a level that is at least as high as a level of the aqueous reaction solution in the measurement cell. A melting point of the water is higher than the melting point of the aqueous reaction solution and a boiling point of the water is lower than the boiling point of the aqueous reaction solution so that a temperature in the measurement cell is stabilized between the melting point and the boiling point of the aqueous reaction solution, upon the ozonesonde reaching the stratosphere, by a transfer of energy to or from the aqueous reaction solution in a thermodynamically passive process in an earlier phase transition of the water before a reaching of a triple point of the water.

摘要： An apparatus and method for taking absorbance-based chemical measurements are described. In a specific embodiment, an indicator-based pCO2 (partial pressure of CO2) sensor displays sensor-to-sensor reproducibility and measurement stability. These qualities are achieved by: 1) renewing the sensing solution, 2) allowing the sensing solution to reach equilibrium with the analyte, and 3) calculating the response from a ratio of the indicator solution absorbances which are determined relative to a blank solution. Careful solution preparation, wavelength calibration, and stray light rejection also contribute to this calibration-free system. Three pCO2 sensors were calibrated and each had response curves which were essentially identical within the uncertainty of the calibration. Long-term laboratory and field studies showed the response had no drift over extended periods (months). The theoretical response, determined from thermodynamic characterization of the indicator solution, also predicted the observed calibration-free performance.

摘要： To balance ozone sensors for the onboard diagnosis of a catalytic element which is arranged in a vehicle and is exposed to an ambient airstream, for breaking down ozone, predetermined enable conditions allowing the sensor balancing to be carried out are checked, and if the enable conditions are fulfilled the values of the output signals from the ozone sensors are recorded and compared with one another. This comparison gives a deviation value which is characteristic of the deviation between the two values, and the deviation value is used to decide whether sensor balancing is required and indeed possible. If sensor balancing is required and possible, the values of the output signals from the ozone sensors are compared with a threshold value and depending on the result of this comparison either an additive or a multiplicative correction of the values of the output signals is performed.

摘要： The oxygen sensor of the present invention has excellent durability capable of effectively preventing contamination with lead or the like for a detection electrode even in low temperature exhaust gases, and having stable response over a long period of time. The contamination preventive layer provided in the sensor device comprises composite powders having coarse powders covered therearound with fine powders, and hollows not filled with fine powders are scattered in gaps among the composite powders. Both the coarse and fine powders comprise ceramic powders. Further, it is particularly preferred that the ceramic powders are powders of a titania powder having a peak at 1 &mgr;m or less and a composite ceramic powder containing alumina such as spinel having a peak at 10 &mgr;m or more. The contamination preventive layer can be formed by coating a slurry containing ceramic powders of different specific surface areas, an organic binder and a solvent such as methanol on the surface of the electrode protection layer followed by drying.
