A carrier material having an internal channel

Abstract

There is provided a cartridge (100) for use in an aerosol-generating system (10) for the generation of an aerosol comprising nicotine salt particles. The cartridge (100) comprises a first compartment (110) containing a nicotine source (210) comprising a first carrier material (211) impregnated with nicotine, the first compartment (110) having a first air inlet (132) and a first air outlet (133). The first canier material (211) defines a first airflow channel (215) extending through the first canier material (211). The first airflow channel (215) defines a first airflow path (217) extending along the first airflow channel (215) between the first air inlet (132) and the first air outlet (133). The first airflow channel (215) has a cross-sectional area (219) perpendicular to the first airflow path (217). The cartridge (100) also comprises a second compartment (120) containing an acid source (220) comprising a second carrier material (221) impregnated with an acid, the second compartment (120) having a second air inlet (134) and a second air outlet (135). The second carrier material (221) defines a second airflow channel (225) extending through the second carrier material (221). The second airflow channel (225) defines a second airflow path (227) extending along the second airflow channel (225) between the second air inlet (134) and the second air outlet (135). The second airflow channel (225) has a cross-sectional area (229) perpendicular to the second airflow path (227). The first compartment (110) and the second compartment (120) are arranged in parallel within the cartridge (100). The cross-sectional area (219, 229) of at least one of the first airflow channel (215) and the second airflow channel (225) varies in a direction along the first airflow path (217) or the second airflow path (227) respectively.
