Abstract: In an optical measurement method, light is directed from a light generator to a light path cell. A light path is generated by continuously reflecting the light between first and second high reflection mirrors within a light path cell that face to each other. An optical signal is detected from an aerosol sample present within a range of the light path. The optical signal is separated into a particle signal and a gas signal by using a statistical methodology. A particle concentration is calculated from the particle signal by using an assumption of an optical particle counter (OPC). A gas concentration is calculated from the gas signal by using optical characteristic data of gas.

Abstract: A chemical filter includes a first buffer layer, at least one first filter layer disposed on the first buffer layer and including a pair of first air-permeable bodies facing each other and at least one first adsorption layer between the pair of first air-permeable bodies, and a second filter layer disposed on the first filter layer and including a pair of second air-permeable bodies facing each other and at least one second adsorption layer between the pair of second air-permeable bodies, wherein the first filter layer is configured to be attachable to and detachable from the second filter layer.
