The method and the device measure a fluorine-based gas in a sample containing a corrosive gas with a Fourier transform infrared spectrophotometer, wherein the Fourier transform infrared spectrophotometer includes a detector having an InGaAs detection element and a single-path gas cell having an optical path length of 0.01 m to 2 m, a cell window is made of a corrosion-resistant material, a measurement region ranges from 3800 to 14300 cm−1 in wavenumber, and the concentration of the fluorine-based gas is quantified based on an amount of absorption of light having a predetermined wavenumber by the sample and a calibration curve."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and device for analyzing gas","description":"Provided are a method and a device that do not require any pretreatment and measure and analyze impurities or hydrogen fluoride in corrosive gas with high sensitivity.
