ABSTRACT:
Provided is an apparatus for stabilizing the concentration of a previously generated aerosol, which includes: an aerosol inlet channel; an aerosol pressure adjustment unit accelerating the aerosol; a buffer connected to the aerosol pressure adjustment unit via an aerosol transport channel and having a much larger sectional area than the aerosol inlet channel and the aerosol transport channel, wherein the aerosol accelerated by the aerosol pressure adjustment unit reaches the buffer via the aerosol transport channel and is mixed in the buffer; a feedback channel connecting between the buffer and the preceding channel to the buffer to feedback a portion of the aerosol present in the buffer to the preceding channel to the buffer; and an aerosol outlet channel releasing the aerosol uniformly mixed in the buffer. Provided is also a method for stabilizing the concentration of an aerosol according to the same principle as in the apparatus.
