Computer-implemented methods and computer-readable media are disclosed for providing a spectroscopic film selection tool to select one or more of a plurality of films for use in a spectroscopic analysis. At a first computing system, a spectroscopic film selection tool is stored in a non-transitory storage medium. The spectroscopic film selection tool includes a set of machine-readable instructions configured to execute on a second computing system. The machine-readable instructions are configured to elicit user input regarding attributes of a spectroscopic analysis and, based on the user input, identify one or more of a plurality of films for use in a spectroscopic analysis based on film data for each of the plurality of films. The film selection tool also includes a store of the film data for each of the plurality of films including data relating to suitability of each of the plurality of films including a film type, a film thickness, a chemical resistance to one or more types of chemicals, and energy transmittance properties. The first computing system is communicatively coupled with a network from which the second computing system is able to download the spectroscopic film selection tool. Following the download of the spectroscopic film selection tool at the second computing system, a user of the second computing system is able to execute the spectroscopic film selection tool on the second computing system.

A particulate matter sensor is provided that can include: an insulating substrate; a plurality of sensing electrodes which are disposed on one surface of the insulating substrate and spaced a predetermined interval from each other so as not to be electrically connected to each other; a connection electrode disposed to be coplanar with the plurality of sensing electrodes and connected to a connection terminal formed on the one surface of the insulating substrate to be connected to some or all of the plurality of sensing electrodes through deposited particulate matter; a plurality of terminals formed on the one surface of the insulating substrate and connected one-to-one with the plurality of sensing electrodes and the connection electrode; and a heater unit disposed inside the insulating substrate and configured to provide heat for removing the particulate matter deposited on the sensing electrodes.

A passive microscopic Fabry-Prot Interferometer (FPI) sensor an optical fiber a three-dimensional microscopic optical structure formed on a cleaved tip of an optical fighter that reflects a light signal back through the optical fiber. The reflected light is altered by refractive index changes in the three-dimensional structure that is subject to at least one of: (i) thermal radiation; and (ii) volatile organic compounds.

An optical measurement cell including first and second translucent members, which sandwich an internal space storing test liquid, are configured so that light incident on the first translucent member passes through the internal space and is emitted from the second translucent member. The cell includes a first holding member that holds down the circumference of a light transmission area on an outward surface of the first translucent member; a second holding member that holds down the circumference of a light transmission area on an outward surface of the second translucent member; and seal members that are respectively interposed between the first translucent and holding members and between the second translucent and holding members. In addition, areas excluding parts of surfaces of the respective translucent members are coated with coated films, and the end parts of the coated films are positioned on light transmission area sides of the seal members.
