Describes the periodic injection techniques which enable a concentration range of each component of between 10 to the minus 6 and 10 to the minus 2 with 1 % variability to be obtained. The concentration is expressed as a volume ratio. Includes reference, principle of the method, practical example, operating conditions of the example, estimation of volume ratio, calibration of the system and sources of error and numerical example: Binary mixture of methane in nitrogen.
