Abstract: Because of their unique effect on environment and climate, and the harm to human health, organic carbon and elemental carbon in aerosols drawn growing concern by environmental scientists all over the world. There are many techniques to measure them; however, due to the different experimental principles, the results appeared distinct deviation from each other. For the ThermoOptical methods, with the totally same experimental principle, the EC measured by two machines from different factories, TOT and TOR, have an obvious difference, reaching 70%~80%. This paper introduces measurement methods applied to EC and OC analysis nowadays, including Optical Method and Thermo Method (ThermoOptical Method) to demonstrate their advantages and disadvantages, and to give an expectation for EC and OC in upcoming research.
