 Note

 

For  a  high  accuracy 
measurement,  a  low 
speed 

smaller 

than 

1.0µl/s is advisable.

EAT  cells,  Speed 
= 20µl/s 
 

Adjustment

  

 
By means of the speed value, the sample speed (in 
terms of µl/s) is set. 
 
The  speed  value  can  be  increased  (decreased)  by 
clicking into the corresponding field in the instrument 
settings  box  and  using  the  Right (Left)  buttons  (see 
Fig. 4). 
 
The  count  rate  increases  with  elevated  speed 
values. If the speed is increased too much, peaks in 
the  histograms  may  become  wider  as  a  result  of 
decreasing accuracy. 
 
If the speed is too low, particle sedimentation effects 
can influence a counting result. 
 

Typical Speed Values 

a) High accuracy measuremens  
(e.g. DNA with < 1.5% CV): 
Speed = 0.5 µl/s. 
 
b) Fast measurements and absolute counting: 
Speed = 4.0 - 10.0 µl/s
