It is the region between 1 and 10 microns particle size that is crucial to accurate early detection of severe wear conditions.
Oil Analysis vs. Microscopic Debris Analysis: When and Why to Choose
You'll from figure 3 that Rotrode analysis sits right in the sweet spot for detecting severe and advanced wear particles, although it can miss the larger Catastrophic particles.
RI RS4, when I look at fig3 in the linked document, it shows the upper detection limits for Emission Spectrography being 10 um, and the upper limit for Rotrode Filter Spectroscopy being 100 um. And Polaris Labs also says the upper limit for ICP is 10 um.

Why do you say that the limit for ICP is 2 um, and for RFS is 10 um?
