Coal desorption subsamples are crushed in a sealed ring mill and the released methane gas is measured to determine the residual gas content (Q3).

Desorbed gas measurements (Q2) are taken regularly in our climate controlled field laboratory

Desorption measurements are used to calculate a Q2 desorbed gas versus time plot
