What I heard was second hand, so I can't give too much information, but
there seems to be some red scattering in the old flow cells. The old optics
are also not optimized for Red fluorescence, so for dim fluorochromes, they
may be a problem. I am aware that Coulter does have an upgrade for this. I
need to investigate the problem further and talk to the people my
investigator talked to about the Red fluorescnece problem on the Elite. If
I find out anything more, I will post it to the list.
