Article Synopsis
- The study focuses on the xenon breakthrough curve, which is crucial for understanding how xenon is concentrated from the atmosphere.
- It introduces a new method for analyzing these curves under specific sampling conditions, leading to improved theoretical insights.
- The findings include derived prediction equations that align well with experimental results, showing retention and breakthrough times for xenon at various flow rates in a carbon molecular sieve column.
GC is usually used for xenon concentration and radon removal in the International Monitoring System of the Comprehensive Nuclear-Test-Ban Treaty. In a gas chromatograph, the injection volume is defined to calculate the column capacity. In this paper, the injection volume was investigated and a fitting formula for the injection volume was derived and discussed subsequently.

To improve the capability for xenon sampling from the atmosphere, sampling techniques have been investigated in detail. The sampling techniques are designed by xenon outflow curves which are influenced by many factors, and the injecting condition is one of the key factors that could influence the xenon outflow curves.

Data have been recorded at regular time intervals during measurements covering more than nine times the respective half-lives. This article describes in detail the principle and process of the position relay method with two HPGe detectors.
