NapaGold/Wix and Baldwin filters: Micron Ratings in Filters …
For example, a nominal micron rating of 10 microns at 95% means that the filter media retains 95% of the particles that are 10 microns and larger. Absolute Micron Rating means that the filter is tested using a single pass of contaminants through a filter media and any particles that pass through are measured. You could end up with a 96.7% ...

We find that particles in solution are trapped at a radial position between 1 and 2 microns away from the drop-casted particle. Furthermore, trapped particles undergo rotational diffusion around the drop-casted particle. ... The images are taken in transmission brightfield configuration as described in methods.

Q4. A mixture of silica and gold both having particle
The gold particles are evenly distributed by mass within this particle sizes range (.e., the plot of cumulative mass versus particle size is a straight line). You have been assigned a task to design a separation process (see below a schematic diagram) to separate the gold particles from silica particles. It is required to have pure gold in the ...

Micron Ratings
I honestly don't see why you'd rather have "xx% @ 20 microns" instead of "99% @ xx microns." It makes more sense from both a scientific and pragmatic perspective to list "99% @ xx microns" because with that you're being told: "Essentially every particle this size gets filtered." From there, you can guess/estimate how much it filters at 20 microns, or any number of microns.

Precision Microspheres, Beads, Microparticles, Powder
We define microspheres as spherical particles greater than 1micron and smaller than 1000micron (or 1mm) in diameter. Microspheres with diameters between 1micron and 10micron are larger than nanospheres, but on the bottom edge of microsphere particle sizes, and, therefore, we put them in their own Fine microspheres category.

What Size Particles Cause Wear? | BobIsTheOilGuy
Generally the 5-20 um particles are considered the most damaging. Anything smaller than 5 microns will fit through bearing clearances and causes very little wear. The exception is soot, which can cause "erosive" wear if the fluid is flowing at fairly high velocities. Particles > 20 microns tend to be removed by the oil filter on the first pass. TS

Replating, Gold Thickness and Microns | Article
Microns measure the thickness of gold plating: 1 micron: 0.001 of a millimetre. Heavy gold plated: 2.5 microns and up (if on silver, also called vermeil, but more on this later) For comparison, a human hair is roughly 75 microns in diameter. For the term "gold-plated" to be used, the layer of gold has to be equal or greater than 0.5 micron.
