Series: Comparing Particle Loss in Transport Tubing for Instruments with Different Flow Rates

Written by

In this series, a particle counter's ideal flow rate is examined through the lens of particle loss in connecting tubing. The mathematical basis for particle loss causation is discussed and applied to the results of testing a 100 LPM device for 0.5 um and 5.0 um particle losses within 2 m tubing.

Troubleshooting for Liquid Particle Counting Series

Written by

The previous post of the Troubleshooting for Liquid Particle Counting series was about the effects of background scatter on particle count data. This segment defines an OPC’s upper concentration limit, its role in coincidence loss, and concludes this blog series. To read the full paper, click here.
