Application Summary AI generated

This standard specifies the diffusion method for preparing calibration gas mixtures using dynamic volumetric techniques. It is applied in chemical analysis and environmental monitoring laboratories to generate precise, low-concentration gas standards for calibrating gas analyzers and sensors. The method is particularly relevant for producing reactive or unstable gas mixtures that cannot be stored in cylinders.
