What particle concentration can MFI measure?
The exact concentration limits depend on sample and particle characteristics and the environmental conditions. However, using 5 µm NIST-traceable polystyrene beads, the upper limit is 275,000 to 800,000 particles per mL depending on the selected optical Set Point. The lower limit is theoretically zero however practical limits are approximately < 20 particles per mL –depending on the operating Set Point.
