PM2.5 online source apportionment mass spectrometry monitoring system
SPAMS 05series
SPAMS 05 series can be used to real time monitor the refractory and fusible substances such as heavy metals, mine dust, black carbon, sulfate and so on in aerosols, simultaneously provide the information of particle size and chemical composition.Furthermore, it is used to study the interaction between aerosol particles and cloud droplets, evaluate the chemical composition and mixing state of single cloud residue particles.It can also be used to study the composition, mixing state and size distribution of sand dust, deepen the analysis of the causes and pollution process of dust pollution in China, and explore the influence of aerosol mixing state on the change of dust particles.
Principles of the instrument

Through high-sensitivity, high-speed and high-resolution TOF-MS, the chemical composition and size of single-particle aerosols can be measured in real-time and online, and the mixing state data of single particles can be obtained, and the source classification of PM2.5 can be realized quickly.
