The amount and type of charge determines where the drop will be sorted. For
example, in a four-way sort, drops with the most charge will be deflected into the
outer streams, while drops with less charge will be deflected into the inner
streams.
Conflict Resolution During Sorting
During sorting, the cytometer deflects drops based on the characteristics of the
particles in each drop and where the user wants to deflect them. Conflicts can
occur depending on the type of target particle, where the particle is located
within a drop, or whether the drop is free of contaminating particles.
BD FACSDiva software accurately measures particle position to within 1/32 of a
drop.
Mask settings determine how drops are deflected
when sorting conflicts occur. There are t hr ee M as k
settings, each of which addresses a different type of
conflict. These settings are combined to define sort
Precision Modes. Each mode is made up of a set of
masks. Precision Modes are defined in the Sort
Precision dialog, accessed from the Sort menu.
