Abstract
Analyzing gas samples wherein the sample is passed into a measurement chamber via a molecular diffusion filter. The composition or pressure of the gas is changed with time as it moves through the filter and a pressure sensor within the measurement chamber is arranged to record pressure changes with respect to amplitude and time due to the difference in diffusion times of the gas components in the measured sample.
