Abstract: The present invention relates to an improvement in spectral analysis in spectrometry, particularly in a technique of spectral analysis by spectral classification at high speed. A spectral analysis device 10 comprises: a measurement unit 20 that measures a sample spectrum of a target sample 30; and an analysis unit 40 that analyses the sample spectrum, and analyses a compound contained in the target sample 30, wherein the analysis unit has a library that is processed with an arithmetic processing in advance, the library has a plurality of compound groups to which the compound is classified, and the analysis unit further comprises an analysis display part 42, the analysis display part 42 displays, in real time, the compound group to which the compound belongs during analysis of the sample spectrum as the analysis progress or analysis result.

Abstract: A snow making apparatus includes: a snow making container having an inner space for snow making; a supply unit configured to supply fine snow or fine water droplets to the inner space; a catching unit configured to catch the fine snow or the fine snow formed of the water droplets; and a drive unit configured to move the catching unit toward a place where the fine snow is flying in the inner space. The catching unit is configured to be shaken thereby making snow caught by the catching unit fall off from the catching unit.

Abstract: A snow making apparatus includes a cylindrical body and a snow making nozzle that jets water droplets into the cylindrical body. The cylindrical body has a proximal end that is opened to a temperature environment where snow can be produced from water droplets jetted from the snow making nozzle. A distal end of the cylindrical body is connected to a pipe member communicating with a test chamber. The snow making nozzle is formed of a two-fluid nozzle. The pipe member communicates with a snowfall hood disposed in the test chamber and having a supply opening that allows snow to fall. The cylindrical body is disposed in an oblique posture so as to be lowered from a proximal end toward a distal end of the cylindrical body.
