In brief, conditioned media or sera were cleared of cells and cell debris by low-speed centrifugation and filtration, followed by concentrating the remaining particulate at 70,000 g for 1 h.

The synovial fluid produced by the synovial membrane is viscous, light yellow, clear, and free of particulate matter, fibrinogen and other coagulation factors [ 4].
During influenza virus infection, loss of ciliated and mucus-producing epithelial cells occurred [ 14] and, due to this, the function of clearing microorganisms and particulate matter is disrupted, so conditioned pathogens can stay in the lung longer and in turn cause a secondary infection [ 15].
Clearance of nanoparticles is usually via the reticulo-endothelial system (RES), and a high particle load could lead to RES overload, thus compromising the body's ability to clear other particulate species.
Doses were visually examined and needed to be clear, colorless and free of particulate matter.
It is not entirely clear whether high levels of particulate matter from such natural phenomena pose the same risks on cardiovascular and respiratory health as particles from anthropogenic sources.
That would reduce the type of rigorous cleaning needed to clear those particulates and make it easier for reusability, said Ann Karagozian, UCLA professor of mechanical and aerospace engineering.
If your hose is not made of a washable material, you'll have to rely on force and wind to try to clear it of any particulate gunk that might have accumulated over many uses.
Applying this principle to the ErA data discussed above, it is clear that the vast majority of particulate matter is in the lower part of the size range between 2 and 10 μm, as shown in Fig. 6 for a typical ErA DP analysis.
