Method of measuring the flux of a soil gas |
摘要 |
A method for determining a flux of a gas contained in a medium through a boundary of the medium comprises 1) measuring at least twice with a probe a concentration C of the gas over a time intervalΔt and 2) determining the flux of the gas using the following mathematical equation: (I) where F is the gas flux, D is the diffusivity value andΔC is a variation in the gas concentration during the time intervalΔt. The probe is placed proximate the boundary. The probe has a gas inlet, a cavity, a gas concentration sensor and a membrane. Each element is in fluid communication with each other so that the gas flows from the gas inlet through the membrane and contacts the gas concentration sensor. |
