… background in a histogram? 

Histograms sometimes show undesired signals in the lower channels, frequently called ´noise´ or 
´background´. These signals may originate from cell fragments or other particles resulting from sample 
preparation. In case of high signal amplification, background can also be caused by particle contaminated 
sheath fluid. 

The lower level (L-L) or threshold?  

The lower level (L-L) threshold is a mean to suppress background signals. Signals below the lower level are 
rejected from the signal acquisition. To exclude noise from a histogram already acquired, a region-gate can 
be used.
