AI Technical Summary
Existing pressure-based preparation techniques cannot simultaneously achieve accurate control of carbon dioxide concentration and carbon stable isotope values, and are not adaptable enough to changes in environmental conditions, resulting in unstable preparation accuracy and complex operation procedures, making it difficult to meet the requirements of high-precision observation.
By acquiring the basic parameters of gas distribution, and based on the conservation of carbon dioxide mass and the conservation of carbon stable isotope mass, the target pressure and partial pressure are calculated. High-concentration raw material gas and ambient atmosphere are introduced step by step. Combined with real-time monitoring and quantitative ring flushing, the uniformity of gas components is ensured, making it compatible with conventional pressure method preparation devices.
It achieves simultaneous and accurate control of carbon dioxide concentration and carbon stable isotope values, improves the environmental adaptability and ease of operation of the preparation process, ensures the stability, consistency and high precision of standard gas parameters, and is suitable for different application scenarios.
