A micron is equal to one-millionth of a meter (μm). There are many ways to measure pore size; however, most manufacturers use a laser diffraction method called “grazing incidence small angle x-ray scattering” to determine pore sizes.

In terms of how low to pull a vacuum, it is irrelevant. WebIn many image analysis methods for particle measurement, each particle is recorded only once in random orientation. Especially for particles with a defined geometry, such as lenses or rods (e.g.: extrudates), it is very likely that the relevant projection is not captured during the acquisition: for example, rods tend to be measured "too short" with random orientation.
