A simple method is described for the separation of mixtures of CH 4 , N 2 O, CO 2 , N 2 , and O 2 in soil atmospheres using a single sample. This method uses two columns of Porapak Q at different temperatures but requires only one detector and recorder. Total analysis time is 23 min, but samples can be injected every 17 min without conflicting peaks.
