GC is usually used for xenon concentration and radon removal in the I nternational M onitoring S ystem of the C omprehensive N uclear‐ T est‐ B an T reaty. 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. As a consequence, the xenon injection volume exponentially decreased with the column temperature increased, but exponentially increased as the flow rate increased.
