METHOD FOR RECORDING LUMINESCENCE AND SCATTERING SIGNALS FROM AEROSOL PARTICLES WHEN THEY ARE EXCITED IN A JET AND A SYSTEM FOR ITS IMPLEMENTATION Russian patent published in 2023 - IPC G01N21/64 G01N21/53 

FIELD: instrumentation.

SUBSTANCE: invention relates to the field of instrumentation and relates to a method for recording luminescence and scattering signals from aerosol particles when they are excited in a jet. The method includes illuminating an air flow with an aerosol by an exciting beam, collecting and separating optical signals of scattering and luminescence into at least three channels in a spectral separation unit, and directing the signals to optical radiation receivers. In this case, the collection axis of scattering and luminescence optical signals is perpendicular to the axis of the exciting beam. When implementing the method, an air flow of an aerosol jet is formed in the analyzed volume of the flow-optical chamber, into which air flows come from an air flow driver. The speed that is optimal for the passage of aerosol particles of certain sizes in the analyzed volume is determined in the electronic control unit based on data from optical radiation receivers.

EFFECT: increasing sensitivity and enabling the detection of aerosol particles of small cross section.
