acquisition - total or gated events per sec limit?

Greatings again,

In my samples from patients whose RBC's don't lyse, we use CD45 to
gate out the lymphs. But, when I acquire, I get ~ 3000-5000 total
events per second (my actual CD45 gate picks up only 100-200 events
per second).

I know I can set thresholds etc, to eliminate the non-CD45 stuff, but
the fact that there are 4000 cells going through the lasers in
addition to my 100 cells of interest each second makes me worry
whether or not the Cytometer is keeping an accurate count.

The model I use is the good ol' FACSCalibur. Input from folks at BD
is especially appreciated.

thanks a million (cells per sec)

Maciej
