Real time particle fluorescence detection device

摘要

The present invention relates to a device for real-time fluorescence detection having a particle concentrator (100) adapted to separate and concentrate the aerosol particles and a particle measuring unit (200) disposed on the underside of the particle concentrator (100). The particle measuring unit (200) includes: an inlet part (210) adapted to introduce the particles and air from the particle concentrator (100) thereinto; an optical chamber (220) having a particle measuring space formed at the interior thereof; a beam shaping part (250) adapted to illuminate the particles in the measuring space with a laser beam; a beam dump part (260); a pair of reflectors (230) disposed in the particle measuring space at an angle of 90° with respect to the forward direction of the laser beam; a particle discharging part (240) adapted to discharge the particles and air to the outside; and a beam splitting part (270) having a scattering light detector (274) and fluorescence detectors (272, 273). adapted to detect scattering light and fluorescence light produced by the interaction between the laser beam and the particles.
