US Patent 11427775 Integrated preparation and detection device for biomass-burning aerosol and method thereby

Disclosed herein are integrated preparation and detection devices for studying biomass-burning aerosols, where the devices include a micro-fluidized bed reactor (MFBR), a transmission line, and an on-line detection unit that are connected in sequence. The MFBR may include a pyrolysis reactor and a pyrolysis furnace; the pyrolysis reactor may include a thermocouple, an introduction tube, and quartz sands; the on-line detection unit may be an on-line photoionization mass spectrometer; and the photoionization mass spectrometer may include a laser desorption system, a laser ionizer and a light energy ionizer. Devices of the present disclosure are beneficial to retain the original state of aerosol particles, and the fixed MFBR can realize rapid pyrolysis of a biomass due to its high and stable heat conduction efficiency, which is beneficial to studying the formation mechanism of aerosol particles.
