Comparison between the Completely Extractable Cold-Drying Method and Hot-Wet Method In the CMES (Continuous Mercury Emission Monitoring System) gas analyzer, the fully extracted cold-dry method and the fully extracted hot-moisture method are two different gas sampling and processing methods. They have different characteristics when processing and analyzing gas samples and applications. Here’s a comparison of the two methods: 1. Complete extraction cold-drying method: Principle: This method in CEMS Gas analyzers condenses and removes moisture in the sample gas through cooling. This prevents water vapor from interfering with gas analysis. Advantage: Reduce water vapor interference: Remove moisture by cooling the sample gas. This method effectively reduces the interference of water vapor on gas analysis results. This is an important advantage for analytical projects where moisture may cause chemical reactions or physical absorption. Enhance analytical accuracy: The removal of water vapor helps improve the detection accuracy of certain gas components, especially in applications that pursue high- precision analysis, such as trace gas analysis. Avoid equipment problems caused by water vapor: Water vapor may cause corrosion or other damage to components of some analytical instruments. This risk can be reduced by freeze-drying. Wide applicability: Suitable for various gas analyzes that require dry sample gas, such as VOCs (volatile organic compounds) analysis, trace gas analysis, etc. Read more: https://esegas.com/comparing-cems-methods-based-on-different-principles-a- revolutionary-advance-in-real-time-environmental-monitoring/
