In the same context, the number A can be considered to include numerical values that are within the normal measurement standard error of a property that modifies the number A. In some cases, the number A at used in the appended claims may deviate by the percentages expressed above in numerical form, provided that the amount by which A deviates does not significantly affect the main and new characteristic (characteristics) of the claimed invention. In addition, all ranges include the disclosed minimum and maximum points and any intermediate ranges within them, which may or may not be specifically expressed in numerical form in this document.

A device according to any one of the preceding claims, further comprising a mouthpiece that is removably attachable to the proximal end of the upper portion without placing an aerosol generating article in said cavity. 5. An apparatus according to any one of the preceding claims, wherein both of the cartridge top connector and the cartridge main connector comprise electrically conductive members configured to provide electrical contact between the top and body when the cartridge top connector is directly attached to the cartridge main connector according to the second mode of operation. . 6. An apparatus according to any one of the preceding claims, wherein the top heating element comprises an induction heating element. 7. The device according to claim 6, wherein the induction heating element comprises a peripheral inductor and a tubular current collector surrounding at least a portion of the upper airflow channel. 8. The device according to claim 7, wherein the upper part comprises an upper air inlet and an additional air flow channel extending from the upper air inlet to said cavity, wherein the induction heating element comprises an additional tubular current collector surrounding at least a portion specified cavity. 9. The device according to claim 8, in which the inductor, the tubular pantograph and the additional tubular pantograph are coaxially aligned. 10. An apparatus according to any one of the preceding claims, wherein the top comprises a wick located at least partially within the top airflow channel at a distance from the distal end of the top airflow channel. 11. The device of claim 10 wherein the wick is a porous element. 12. The apparatus of any one of the preceding claims, wherein the body comprises a high retention material positioned proximate the main cartridge connector to absorb potential leaks from the cartridge. 13. An apparatus according to any one of the preceding claims, wherein the liquid outlet at the proximal end of the cartridge comprises a one-way valve. 14. An apparatus according to any one of the preceding claims, wherein the air inlet at the distal end of the cartridge comprises a one-way valve. 15. An apparatus according to any one of the preceding claims, wherein the liquid storage portion of the cartridge contains a sensory liquid medium. 16. The device according to claim 15, in which the liquid medium perceived by the senses contains a flavoring substance. 17. The device according to claim 15 or 16, wherein the sensory fluid contains nicotine. 18. An apparatus according to any one of the preceding claims, wherein the liquid storage portion of the cartridge comprises two or more liquid storage compartments connected in series. 19. An apparatus according to any one of the preceding claims, wherein the liquid storage portion of the cartridge comprises two or more parallel connected liquid storage compartments. 20. The apparatus of claim 18 or 19, wherein at least one liquid storage compartment contains a liquid composition that is different from the liquid composition of the other liquid storage compartment. 21. An apparatus according to any one of the preceding claims, wherein the cartridge comprises electrically conductive members configured to provide electrical contact between the top and body when the cartridge is attached to both of the top and body. 22. An aerosol generating system comprising an apparatus according to any one of the preceding claims and an aerosol generating article comprising an aerosol generating substrate.
