Sorting bacteria expressing gfp on a Coulter Epics Elite

Hello, 

I am currently sorting bacteria expressing a promoter trap fusion library to
gfp on a Coulter Epics Elite.  I am interested in talking to anyone who is
sorting bacteria on this machine.  More specifically, I am having trouble
separating non-fluorescent bacterial cells from those cells which are weakly
fluorescing.  I am able to successfully sort bacterial cells expressing gfp
strongly from non-fluorescing bacterial cells; however, I am unable to sort
non-fluorescing cells from those cells weakly expressing gfp.  I think I am
having this problem because the weakly fluorescing cells are overlapping
into the non-fluorescent region (this non-fluorescent region was determined
by using a non-fluorescent control).  Any help anyone could give me would be
great.  

Thanks, Janet
