A resin composition quality controlling method includes a step of measuring a Raman spectrum of a resin composition composed of TiO.sub.2 particles dispersed in a base material mainly composed of a silicone rubber by irradiating the resin composition with laser, and a step of determining a concentration of the TiO.sub.2 particles in the resin composition based on an intensity of a fluorescence spectrum in the Raman spectrum.

A method and device for examining rod-shaped products of the cigarette industry, having a cylindrical lateral surface and two end faces formed by two filter elements arranged at opposite ends, the product having smokable material between the two end faces, by: a) irradiating the lateral surface using examination light whereby the examination light penetrates through the lateral surface at least partially into the product and at least partially exits again through one end face, the beams of which are incident on the lateral surface at an angle of at least 30° in relation to the longitudinal extension of the product; b) acquiring the examination light exiting the end face of the product using an electro-optical receiver, the main viewing direction of which is directed onto the end face; and c) evaluating the brightness or light intensity of the examination light exiting the end face and acquired by the electro-optical receiver.

The invention also relates to the applications of these electrospun fiber assemblies in biological applications, and method of manufacturing these electrospun fiber assemblies.

The present disclosure relates to a bipolar plate for an electrochemical system, comprising two separator plates which are connected to one another, at least one of the separator plates having a plate body and at least one tab which is formed in one piece with the plate body and can be separated from the plate body via a predetermined breaking point. The disclosure additionally relates to a retention sample for a bipolar plate or flow plate, to a flow plate, to a system, and to a method for producing and testing a bipolar plate or flow plate.

The present invention relates to a device and a method for evaluating performance of a deodorant using a superabsorbent polymer (SAP), and the device and method are capable of quantitatively evaluating deodorant performance by collecting ammonia adsorbed to deodorant materials including the SAP and measuring the amount of ammonia thereof.

A quality control apparatus includes: a test value acquisition unit that acquires test values of respective components that constitute a product; an assembling management information acquisition unit that acquires assembling management information that is information concerning assembling of the product and the components; a step-related information acquisition unit that acquires step-related information that is information related to a production step; and a display that displays a configuration diagram of the product that is hierarchically constituted by the components and shows a combination of elements that are assumed to be likely to have caused a quality defect of the product on the configuration diagram on a basis of the test values, the assembling management information, and the step-related information.

Provided are methods of evaluating deodorizing ability of a superabsorbent polymer and a product including the same. According to the methods of evaluating deodorizing ability of the present invention, deodorizing ability of the superabsorbent polymer and the product including the same may be evaluated by measuring changes in the concentration of ammonia naturally generated in a wet state which is made close to the actual use environment. Accordingly, the deodorizing ability of the superabsorbent polymer and the product including the same may be evaluated more accurately and efficiently.
