How do I increase the particle rate?

Particle rate depends on the concentration of the prepared sample (or calibration) particles as well as the applied pressure. 

We recommend for the particle rate to be between 200-1500 particles/min. 

If the rate is higher than the value above, the likelihood of coincidence events to occur is higher. A coincidence event is when more than one particle passes through the sensing zone at once. If the particle rate is higher than recommended, the software will overestimate the calculation for mean size and underestimate the calculation for particle concentration.
