Abstract: To more accurately output a signal related to a source of particulate matter floating in the atmosphere, an analyzer is equipped with a mass concentration measuring unit, an element analysis unit, and a source-related signal output unit. The mass concentration measuring unit measures the mass concentration of fine particulate matter (FP) in the atmosphere. The element analysis unit analyzes an element contained in the FP. The source-related signal output unit outputs a signal related to the source of the FP on the basis of the mass concentration measurement result from the mass concentration measuring unit, and the analysis result for the element contained in the FP from the element analysis unit.

Abstract: In an analyzing apparatus for analyzing compositions using a fluorescent X-ray in the atmosphere, a calibration to eliminate influences caused by a time-dependent change is performed. The analyzing apparatus includes an emission unit, a detection unit, an environment measurement unit, and a time-dependent change calculation unit. The emission unit emits a primary X-ray. The detection unit detects an intensity of a secondary X-ray passing through the atmosphere. The environment measurement unit measures an environment parameter defining the atmosphere. The time-dependent change calculation unit calculates a time-dependent change of the intensity of the secondary X-ray between a first timing and a second timing, based on a first environment parameter, a first intensity of the secondary X-ray, a second environment parameter, and a second intensity of the secondary X-ray.

Abstract: This invention provides a zero gas refiner for CO2 concentration measurement device that can continuously refine a zero gas that is preferable for CO2 concentration measurement. This invention adopts the zero gas refiner comprising a water adsorbent and a CO2 adsorbent that desorb an adsorbed component and restore an adsorption ability by being heated to a predetermined restoration temperature, a refiner body that adsorbs water and CO2 in an introduced sample gas or air in this order by the use of the water adsorbent and the CO2 adsorbent housed inside of the refiner body so as to refine a zero gas and that leads out the zero gas, and a heating mechanism that applies heat to the refiner body at a time when the adsorption ability of the water adsorbent or the CO2 adsorbent drops to an amount that is less than or equal to a predetermined amount.

Abstract: A gas analyzing apparatus includes a gas analyzing unit, a luminescence inducing component generating unit, and a measurement signal calculating unit. The gas analyzing unit receives a sample gas containing a component gas and/or a standard gas and the luminescence inducing gas. The gas analyzing unit is configured to output a detection signal based on an intensity of a reaction light generated by the interaction between the component gas and the luminescence inducing component. The luminescence inducing component generating unit generates the luminescence inducing gas by electric discharge generated repeatedly at specified intervals. The measurement signal calculating unit calculates a first measurement signal based on a first detection signal, based on the reaction light generated when the sample gas and the luminescence inducing gas are introduced, and a second detection signal, based on the reaction light generated when the standard gas and the luminescence inducing gas are introduced.
