Abstract: There is provided a cartridge for an aerosol-generating system, the cartridge including: a first compartment having a first air inlet and a first air outlet, the first compartment containing a nicotine source including a first carrier material impregnated with between about 1 milligram and about 40 milligrams of nicotine; and a second compartment having a second air inlet and a second air outlet, the second compartment containing a lactic acid source including a second carrier material impregnated with between about 2 milligrams and about 60 milligrams of lactic acid. An aerosol-generating system is also provided, including the cartridge and an aerosol-generating device including a housing defining a cavity configured to receive at least a portion of the cartridge; and a heater configured to heat the first compartment and the second compartment of the cartridge.

Abstract: A cartridge assembly for an aerosol-generating system is provided, including a cartridge having upstream and downstream ends, a first compartment having a first air inlet and a first air outlet, and a second compartment having a second air inlet and a second air outlet; a cartridge holder, a portion of the cartridge being received within the cartridge holder; a mouthpiece having upstream and downstream ends, at least a portion of the cartridge holder is received within the mouthpiece, the downstream end of the cartridge is spaced apart from the downstream end of the mouthpiece and defines a mixing chamber therebetween, and another portion of the cartridge holder is spaced apart from the mouthpiece and defines an airflow channel between the cartridge holder and the mouthpiece; and a ventilation air aperture providing fluid communication between a downstream portion of the airflow channel and the mixing chamber.

Abstract: An aerosol-generating system is provided, including a housing having a first portion and a second portion. The housing includes an air inlet; a nicotine source; a volatile delivery enhancing compound source; and an air outlet. The first portion of the housing and the second portion of the housing are movable relative to one another between an open position and a closed position. In the open position, the air inlet and the air outlet are unobstructed and the nicotine source and the volatile delivery enhancing compound source are both in fluid communication with an airflow pathway through the housing between the air inlet and the air outlet. In the closed position, either the air inlet is obstructed or the nicotine source and the volatile delivery enhancing compound source are both not in fluid communication with an airflow pathway through the housing between the air inlet and the air outlet or both.

Abstract: An aerosol-generating system is provided, including a nicotine source, a lactic acid source, and a single heater configured to heat both the nicotine source and the lactic acid source. The aerosol-generating system may also include an aerosol-generating article including a cartridge having a first compartment including the nicotine source and a second compartment including the lactic acid source; and an aerosol-generating device including the single heater. The cartridge may also include a cavity configured to receive the single heater of the aerosol-generating device.
