bulk removal of dead cells

Is there any perfect method to bulk isolate a small number of vital cells
from a much larger population of dead and dying cells (apoptotic, necrotic,
debris) ?

It would have to be quantitative.

There is lysis of dead cells by protease. Does that safely preserve all
viable cells ? If yes, what are the best conditions ?

I was told it can be done by density gradient, but I cannot figure out how
that should work.

Many thanks for your opinions.
