Method for measuring the additive content (% by volume or by weight) in a tobacco paper for electronic cigarettes, which is made from a mushy mass of additives, water, flavorings and tobacco, the mushy mass being dried to form a single-ply tobacco paper, wherein the tobacco paper is measured with at least one microwave resonator, is measured with two resonance modes with two resonance frequencies (f L , f H ), the smaller of the two resonance frequencies (f L ) being in the frequency range with less than 1 GHz and the larger of the two resonance frequencies im microwave range with more than 2 GHz, a density-independent moisture angle Φ L,H is calculated for each of the two resonance modes, the glycerol content g is determined as a function of the two moisture angles. |
