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.

Method of analysis of gasses and gas mixtures where a gas which is to be analyzed is linked via a molecular diffusion path to a measurement chamber in which a pressure sensor registers pressure changes, wherein the pressure of gas (1) is modulated and wherein the pressure sensor (3) registers pressure changes according to their amplitude and time, which arise due to the different diffusion times of different gas components.
Device for analysis of gases and gas mixtures with a gas supply system (7,8,10), through which a gas which is to be analyzed (4) is connected via a molecular diffusion path (2) to the gas supply system (7,10) and where a pressure sensor is able to record the pressure changes in a measurement chamber (1), wherein the device is equipped with a gas modulator (6,12,9) through which the gas which is to be analyzed (4) can be modulated in time as to its composition.
