Scanning Electron Microscope (SEM) and Scanning Electron Microscope coupled with
Energy Dispersed X-ray (SEM-EDX) to determinate inorganic foulant elemental
composition.
- Fourier Transform Infrared Spectroscopy (FTIR) to identify organic compounds.
- Targeted Energy Dispersive X-Ray Analysis (T-EDXA) as an indication of inorganic
compounds.
