  • Patent number: 11828688
    Abstract: A system and process for collecting aerosol matter samples is disclosed. The system includes a circular sample cartridge holder that contains a plurality of sample cartridges. Each sample cartridge contains a filter media for collecting aerosol matter samples. The system further includes a docking device for receiving an aerosol-generating system. The docking device places the aerosol-generating system in engagement with one of the sample cartridges. The aerosol matter collecting system further includes an aerosol withdrawing device that causes a controlled puff volume to flow through a sample cartridge for collecting an aerosol matter sample. The system can be completely automated and can collect samples on a puff by puff basis. The system and process are well suited to analyzing aerosols collected heated tobacco product system, but can also be used to test smoking articles, such as cigarettes, or any other device or product such as e cigarette that produces an aerosol.

  • Patent number: 10098378
    Abstract: A smoking article formed from a tobacco material that includes tobacco non-isometric precipitated calcium carbonate microparticles is provided. The non-isometric microparticles typically have a mean diameter of from about 50 nanometers to about 3 micrometers, in some embodiments from about 80 nanometers to about 1 micrometer, in some embodiments from about 100 nanometers to about 400 nanometers, and in some embodiments, from about 200 nanometers to about 300 nanometers. Such non-isometric particles may have an elongated morphology so that the length of the microparticles is greater than the diameter. This may be characterized by the “aspect ratio” of the microparticles (length divided by width), which is typically from about 1 to about 15, in some embodiments from about 2 to about 12, and in some embodiments, from about 3 to about 10.
