ActiveGas analysis—Preparation of calibration gas mixtures using dynamic volumetric methods—Part 4: Continuous syringe injection method
气体分析 动态体积法制备校准用混合气体 第4部分：连续注射法
Application Summary AI generated
This standard specifies the continuous syringe injection method for preparing calibration gas mixtures by dynamically injecting a liquid or gas component into a carrier gas stream at a controlled rate. It is applied in chemical analysis and environmental monitoring laboratories to generate precise, low-concentration gas standards for calibrating analyzers such as gas chromatographs or emission monitors. The method is particularly useful for producing mixtures of volatile organic compounds or reactive gases where static preparation methods are impractical.
