Abstract: There is described an apparatus for heating an aerosol generating material to generate an inhalable aerosol or gas. The apparatus includes a housing; a receptacle within the housing, the receptacle including one or more cavities, each cavity for containing an aerosol generating material; and a heating arrangement including one or more heater elements for heating aerosol generating material contained in the one or more cavities to generate an inhalable aerosol or gas. The one or more heater elements are located externally of the one or more cavities.

Abstract: There is described a cartridge for use with an apparatus for heating aerosol generating material to volatilize at least one component of the aerosol generating material. The cartridge includes a first body defining a first chamber and aerosol generating material is located within the first chamber. The first body includes a first base including a sheet of heat conductive material and has a first outer surface and at least a major portion of the first outer surface is for contacting a first heating surface of a heater of the apparatus for heating the aerosol generating material within the first chamber.

Abstract: An electrochemical cell having co-axial inner and outer electrodes separated by an ion-permeable tube that defines inner and outer passageways for liquid flow lengthwise of the electrodes. The ion-permeable tube has elastomeric caps attached at each end. The elastomeric caps have rims that engage the inner walls of the electrochemical cell to separate the inner and outer passageways and the electrochemical products derived at the inner and outer electrodes.
