Summary:

The advantages of using the scanning electron microscope (SEM) to characterize automotive particles are described. The sample, collected using an Andersen sampler, is bombarded with electrons and the resultant x-rays are analyzed with an energy dispersive spectrometer.After many particles were observed, classifications were made for individual particles of one structural type greater than 3 μ in size; agglomerates, single masses of particles less than 1 μ; fines, particles of 500-1000 Å; and atypical particles.It is felt that with the advances in methods and technology this procedure will provide a strong basis for future sampling characterization and identification
