The Counts (Y axis) scale can be adjusted swiping your finger up or down in the white
histogram area. For low concentration cell samples, it is important to decrease the counts scale
(swipe from the bottom to top) in order to properly view and gate the population.
As the lower display scale (2.7 µm for Type S+ cassettes) is lower than the lower size detection
limit of the system/cassettes, some inherent system noise is inevitably present. To help identify
this noise, the counts in this region are automatically grayed out by the system.
In size-only mode, an MPI value is also provided in the yellow box at the top right of the display.
This value is a measure of the purity of the sample by providing a ratio of the size-gated (or
curve-fit) population to the total particle population (not including the automatically grayed out
noise region). This metric has shown utility in tracking culture health by highlighting increases in
small particle components that inevitably result from cell necrosis or microbial growth.
