Aerosol generator

A method of making an aerosol generator device for delivering an aerosol of a nicotine salt, comprising:

• (i) combining a first chamber containing a porous material wetted with liquid nicotine, a second chamber containing a porous material wetted with a solution of a volatile acid, and a third chamber in fluid communication with the first and second chambers and leading to a mouth end,
• wherein a nicotine vapor can be produced by passing air through the porous material wetted with liquid nicotine,
• wherein an acid vapor can be produced by passing air through the porous material wetted with a solution of a volatile acid,
• and wherein the nicotine vapor and the acid vapor can be admixed in the third chamber to form an aerosol of a nicotine salt, which can be drawn out the mouth end;
• and
• (ii) surrounding the device with an outer housing that defines a passageway for air through said device to form the aerosol generator device.

A method of using an aerosol generator device for delivering an aerosol of a nicotine salt, comprising:

• flowing or drawing air through an aerosol generator device comprising a mouth end;
• a first chamber containing a porous material wetted with liquid nicotine;
• a second chamber containing a porous material wetted with a solution of a volatile acid;
• a third chamber in fluid communication with the first and second chambers, and leading to the mouth end, and an outer housing defining a passageway for the air through said device,
• producing nicotine vapor by passing at least some of the air through the porous material wetted with liquid nicotine,
• producing acid vapor by passing at least some of the air through the porous material wetted with a solution of a volatile acid,
• and admixing the nicotine vapor and the acid vapor in the third chamber to form an aerosol of a nicotine salt, which is drawn out the mouth end.

A method of producing an aerosol of nicotine salts, comprising:

• producing a nicotine vapor by passing air through a porous material wetted with liquid nicotine;
• producing an acid vapor by passing air through a porous material wetted with a solution of a volatile acid,
• admixing the nicotine vapor and the acid vapor to form the aerosol of a nicotine salt, and
• contacting the aerosol with a basic compound in an amount effective to remove acid vapor in the aerosol.
