Online single particle aerosol mass spectrometer RK-TOF-02

The RK-TOF-02 online single particle aerosol mass spectrometer consists of an injection system, a diameter measurement system, a laser ionization system, and a time-of-flight mass analyzer. Firstly, aerosol particles are accelerated and focused into the vacuum system through an aerodynamic lens. In the measuring area, their aerodynamic diameter is measured by two measuring lasers and the ionization laser is triggered to accurately ionize the particles being measured. The positive and negative ions generated by ionization are detected for their chemical composition by a time-of-flight mass analyzer. Meanwhile, by utilizing its embedded source parsing software, PM can be achieved^2.5Online source parsing. Particles entering the instrument are detected one by one and all component information is provided; Use relevant software for cluster analysis to provide source apportionment results.

■Real time monitoring of heavy metals, mineral dust, black carbon, sulfates, and other refractory and soluble substances in single aerosol particles, while providing information on the particle size, chemical composition, and number concentration of atmospheric aerosol particles;

■Implement PM^2.5Online source parsing, no manual operation required, PM can be automatically obtained within 1 hour^2.5Online source parsing results.
