Embodiment Construction
[0045] This detailed description is intended to illustrate the invention in a non-limiting manner, since any feature of an embodiment may be combined in an advantageous manner with any other feature of a different embodiment.
[0046] As mentioned previously, the described method and device of the present invention are intended for immediate and transient detection of the presence and concentration measurement of organic molecules or mixtures of organic molecules, preferably in an aerosol of water droplets.
[0047] Basically, the methods and devices of the present invention use three fundamental physical effects simultaneously:
[0048] Angle-resolved optical Mie scattering, also known as elastic light scattering;
[0049] Raman scattering of water molecules, also known as inelastic light scattering;
[0050] • Laser-induced fluorescence.
[0051] More specifically, the method uses elastic light scattering and fluorescence emission to estimate the number of impurity molecul...

Abstract
The present relates to a measurement device (1) for the detection and / or measurement of particles in a fluid, the measurement device comprising a fluid source (11) for producing a flow of fluid (111) along a fluid flow path, a first laser source (12) positioned for emitting a first laser beam (120) of laser light in a measurement volume of the fluid flow path for light scattering; a scattered light detecting means (13) for detecting a presence of a particle in the fluid flow path through detection and measurement of laser beam light scattered on different angles by said particle, wherein it further comprises a second laser source (14) positioned for emitting a second laser beam (140) of laser light in said measurement volume of the fluid flow path for Raman and fluorescence excitation; a Raman and fluorescence detecting means (15) for detecting a Raman scattering signal emitted by the fluid and a Fluorescence signal emitted by said particle upon excitation by said second laser beam (140).
Description
technical field [0001] The present invention relates to methods and devices for the detection and / or measurement of impurities in water, more particularly, the present invention relates to methods and devices for on-line detection of the concentration of organic impurities in atomized water droplets. The described method and device of the present invention are intended for immediate and instantaneous detection of the presence and concentration measurement of organic molecules or mixtures of organic molecules in an aerosol of water droplets. Background technique [0002] The present invention relates to the field of prevention and / or protection devices for detection and / or characterization of fluid-borne particles such as but not limited to airborne particles such as air pollutants, airborne biological and chemical pollution substances and / or airborne allergens), waterborne particles (such as water pollutants, aquatic biological pollution and chemical pollution), etc. The in...
