Understanding challenges in meeting particulate emission limits, MTI provides enhanced sampling and characterization of particulate matter.
Microbeam utilizes a particle sampler in field testing applications. The impactor size classifies fly ash particles into four size fractions. Each fraction can be analyzed to determine the mass and chemical composition. Microbeam uses its SEM to image and provide chemical analysis of the particles.
The impactor size fractions are >10 to less than 1μm; if needed, some of the stages can be removed from the assembly to make a simpler setup. The particles are collected on 25 mm substrates on the impactor stages, and a 47 mm filter on the back-up filter stage. The impactor is shown at right. An example of mass/size/composition distribution for the particles is shown below.
