Ambient particulate source analysis system consists of three parts: instrument, online data, and source tracing.

Instrument Series:

• XRF Metal Analyzer: Integrating X-ray fluorescence for metal analysis up to 30 elements and beta-ray attenuation model for particulate mass monitoring, thus it would be significantly effective in industry emission tracing.
• Carbon Analyzer: Adopting thermo-photometry principle with TOT/TOR dual optical correction, integration oven of back & front design avoids condensation of high temperature organics before entering into back oven, which further improved precision.
• Soluble Ion Analyzer: Sample gas passes through denuder and soluble gas will be analyzed by ion chromatography first, the aerosol will then be inflated and passing into ion chromatography for analysis on soluble aerosol.
• TOF-MS PM Analyzer: Adopting the single-particle aerosol time-of-flight mass spectrometry that can measure the chemical composition and size of single particles in real-time and respond rapidly to sudden source of pollution. It is generally used for determining pollution source in urban, remote and marine environment or verifying the accuracy of PMF module to provide data report to environmental agency.

Online Data:

All the initial data detected by the instrument will be stored in the big data management platform.

Source Tracing:

Based on online data, data analysis and component analysis will be carried out through chemical equations and algorithms to achieve the purpose of tracking the particles source.
