### Abstract

The invention relates to a method and a system for determining the fractions of a flowing gaseous medium that comprises a known plurality N of known components. The method comprises the steps for determining at least N-1 parameters of a flowing gaseous medium. The N-1 parameters are chosen from a group of quantities comprising mass flow, density, viscosity, and heat capacity. At least N-1 reference values are provided for each of the known N components relating to each of the determined N-1 quantities. The fraction of each of the known components of the supplied gaseous medium is determined through solving of at least N equations. The N equations comprise N-1 equations which describe each determined parameter as a function of the fraction and the reference values, plus an equation that sets the sum of the fractions so as to be equal to 100%.
