Method for determining an additive content in a tobacco paper for electric cigarettes

Abstract

A method is provided for measuring an additive content in a tobacco paper for electric cigarettes produced from a pulpy mass of additives, water, flavoring substances and tobacco that is dried to form a tobacco paper having a single-layer. The method includes measuring the tobacco paper using at least one microwave resonator having two resonance modes with two resonant frequencies (fL, fH). A lower of the two resonant frequencies (fL) is in a range that is less than 1 GHz and a higher of the two resonant frequencies is in a range that is more than 2 GHZ. A density-independent moisture value (ΦL,H) is determined for each of the two resonance modes and a glycerol content (g) is determined depending on two moisture angles.
