MCA can quantitatively analyze the OC, EC (or BC) deposited on the filter and the corresponding carbon components in different temperature and air environments. In the presence of Multiwavelength, it can be applied in different carbon components in source resolution. Multiwavelength light sources measure both reflected and transmitted light, allowing for the reproducibility and comparison of other thermal/optical carbon analysis methods, which provide a good analysis of the related properties of carbon aerosol.
Applications

Strengths
The instrument has its own widely used IMPROVE_A carbon analysis protocol.
Have high optical measurement sensitivity.
The NDIR CO2 detector is used, so no methane converter and hydrogen gas are required for FID detector.
Less helium consumption.
High accuracy during measurement.
LabVIEW-based software provides a more user-friendly interface and instrument control interface.
Ergonomic design for easy instrument maintenance and repair.
