The ASPEX Personal SEM (PSEM) is a tungsten filament scanning electron microscope optimized for automated particle analysis. The system was designed with staging, scan control and detector geometries optimized for sizing and measuring the composition of particles in the 0.5 micrometer to 100 micrometer range. The PSEM is capable of ~1,000 particles per hour throughput when collecting both size and compositional data and ~10,000 particles per hour when collecting only sizing data. The resulting data sets can be mined for population statistics or needle-in-the-haystack type analyses.
