Measuring Subvisible Particles and Aggregates Using FlowCam LO - White Paper

In this white paper, we utilize FlowCam LO to obtain simultaneous Flow imaging Microscopy (FIM) and LO measurements of a single sample. The results demonstrate that LO can undersize or even completely fail to detect highly transparent particles such as ETFE and some protein aggregates that FIM easily detects. These results highlight the importance of pairing LO measurements with an orthogonal technique like FIM.
