SEM-EDS Particulate matter (PM2.5)
Current studies are focused on the use of multiple analytical techniques to assist in the characterization of particulate matter to gain a better understanding of the relationship between anthropogenic emission sources, ambient PM2.5 and health effects. SEM-EDS characterization of PM2.5 colected in filters was performed to analyze the chemical composition of PM and determine the emission source.
Steps to reproduce
A 15 mm diameter punch was cut out from the loaded filter using fabricated punching tool. The sample was placed on a sample holder, in carbon conductive tape. Samples were fixed using compressed dry air to prevent unfixed small particles from flying during the vacuum and potentially damaging the equipment. Images were taken using an accelerating voltage of 15kV with Phenom™ ProX Desktop SEM, Thermofisher. EDS (energy-dispersive X-ray diffraction) detection was performed tin 10 spots to analyze element composition.
