The granted patent (Publication Number: US11828688B2) describes an aerosol matter collection device designed to collect aerosol samples from an aerosol-generating device without combustion. The device includes a sample cartridge holder capable of holding multiple sample cartridges, each containing filter material for collecting aerosol samples. A docking device engages with each sample cartridge consecutively, while an aerosol withdrawing device collects a controlled volume of aerosol matter generated by the aerosol-generating device. The device is equipped with a controller to synchronize the movement of the docking device and sample cartridge holder for efficient sample collection.

Furthermore, the patent details a process for collecting aerosol samples using the device, involving loading material into the aerosol-generating device, moving it into contact with a sample cartridge, withdrawing a controlled puff volume of aerosol, and repeating the process for multiple samples. The process includes automatic control by a controller for adjusting puff volume, puff duration, and interpuff duration. The device's design, with a rotatable sample cartridge holder and a movable docking device, ensures systematic and accurate collection of aerosol samples for analysis and research purposes. The inclusion of an aerosol withdrawing device with adjustable volume adds versatility to the collection process, allowing for customization based on research requirements.
