Researchers Submit Patent Application, "Device And Method For Analyzing A Gaseous Sample, And Raman Spectrometer", for Approval (USPTO 20240280458).

A patent application has been submitted for a device and method for analyzing a gaseous sample, specifically focusing on the measurement of fine quartz dust content in the air. The invention aims to provide a device that can be carried by workers on construction sites to determine their exposure to quartz dust throughout the day. The device uses Raman scattering to analyze the particles in the sample and evaluate their composition. It is designed to be robust, easy to operate, and capable of distinguishing between different forms of silicon dioxide. The patent application provides detailed descriptions of the components and methods involved in the device. [Extracted from the article]
