AbolishedGas analysis―Preparation of calibration gas mixtures using dynamic volumetric methods―Part 6: Critical orifices
气体分析 动态体积法制备校准用混合气体 第6部分：临界锐孔
Application Summary AI generated
This standard specifies the method for preparing calibration gas mixtures using critical orifices within a dynamic volumetric system. It is applied in chemical analysis and environmental monitoring laboratories to generate precise gas mixtures for calibrating gas analyzers, such as those used for air quality testing or industrial process control. The method ensures accurate flow control through sonic nozzles, making it suitable for applications requiring stable, low-concentration gas standards.
