The system further comprises a power source connected to a load network, the load network comprising an inductor for being inductively coupled to the susceptor. The invention also relates to an aerosol-generating article comprising a cartridge comprising a first compartment (11) with a nicotine source and a second compartment (12) with a second substance source and a susceptor arranged between the first compartment and the second compartment. ## Claims ### Claim 1 Aerosol-generating system comprising: a nicotine source; a second substance source; a susceptor for heating the nicotine source and the second substance source; a power source connected to a load network, the load network comprising an inductor for being inductively coupled to the susceptor; and an aerosol-generating article comprising a cartridge comprising a separation wall at least partially formed by the susceptor, the separation wall separating the first compartment from the second compartment, and the susceptor being in direct contact with the nicotine source and the second substance source. ### Claim 2 (depends on 1) Aerosol-generating system according to claim 1, wherein the susceptor is configured to heat the nicotine source and the second substance source to substantially a same temperature. ### Claim 3 (depends on 1) Aerosol-generating system according to claim 1, wherein the susceptor is in direct contact with at least one of the nicotine source and the second substance source. ### Claim 4 (depends on 1) Aerosol-generating system according to claim 1, wherein the second substance source is a lactic acid source and an aerosol generated in the aerosol-generating system comprises nicotine lactate acid salt particles. ### Claim 5 (depends on 1) Aerosol-generating system according to claim 1, wherein the first compartment comprises the nicotine source and the second compartment comprises the second substance source, wherein the susceptor is arranged between the first compartment and the second compartment. ### Claim 6 (depends on 5) Aerosol-generating system according to claim 5, wherein the first compartment and the second compartment are arranged in parallel. ### Claim 7 (depends on 5) Aerosol-generating system according to claim 5, wherein the cartridge comprises a third compartment comprising an aerosol-modifying agent source. ### Claim 8 (depends on 5) Aerosol-generating system according to claim 5, wherein the cartridge is substantially cylindrical and one or both of the opposed substantially planar end faces of the cartridge is sealed by one or more frangible or removable barriers. ### Claim 9 (depends on 1) Aerosol-generating system according to claim 1, wherein a size of a contact surface of the susceptor is the same for the nicotine source and the second substance source. ### Claim 10 (depends on 1) Aerosol-generating system according to claim 1, wherein a size of a contact surface of the susceptor is different for the nicotine source and the second substance source. ### Claim 11 (depends on 1) Aerosol-generating system according to claim 1, wherein the cartridge comprises two opposed end faces, and wherein the first compartment and the second compartment extend from one end face to the other opposed end face. ### Claim 12 (depends on 1) Aerosol-generating system according to claim 1, wherein the susceptor and the inductor extend along the entire length of the cartridge. ### Claim 13 Aerosol-generating article comprising a cartridge, the cartridge comprising: a first compartment comprising a nicotine source; a second compartment comprising a second substance source; a susceptor arranged between the first compartment and the second compartment and a separation wall at least partially formed by the susceptor, the separation wall separating the first compartment from the second compartment, and the susceptor being in direct contact with the nicotine source and the second substance source. ### Claim 14 (depends on 13) Aerosol-generating article according to claim 13, wherein the susceptor is arranged on a symmetry axis of the cartridge. ### Claim 15 (depends on 13) Aerosol-generating article according to claim 13, wherein the susceptor is an elongate susceptor, preferably in the shape of a susceptor strip. ### Claim 16 (depends on 13) Aerosol-generating article according to claim 13, wherein an outer cartridge wall comprises thermally insulating material. ### Claim 17 (depends on 13) Aerosol-generating article according to claim 13, wherein a size of a contact surface of the susceptor is the same for the nicotine source and the second substance source. ### Claim 18 (depends on 13) Aerosol-generating article according to claim 13, wherein a size of a contact surface of the susceptor is different for the nicotine source and the second substance source. ### Claim 19 (depends on 13) Aerosol-generating article according to claim 13, wherein the cartridge comprises two opposed end faces, and wherein the first compartment and the second compartment extend from one end face to the other opposed end face. ### Claim 20 (depends on 13) Aerosol-generating article according to claim 13, wherein the susceptor extends along the entire length of the first compartment and of the second compartment.
