The limits of the system are as follows:
Typically OF2i® “sees” around 1 % of all the particles in the sample. On a sample with very small particles e.g. 200 nm the measuring parameters are set to 4 µl/min and this should enable a measurement of at least 100 to 1000 particles.
If the particles are large (>3 µm) the measuring parameters can be set to 200 µl min.
