For Research Use Only. Not for Use in Diagnostic Procedures.

 

The older Dionex SRC-1  controller has been discontinued.  The replacement product is either 
the Dionex RFC-10 controller or the Dionex RFC-30 controller.  The Dionex RFC-10 controller 
provides 1 mA graduated control of an electrolytic suppressor.  The  Dionex RFC-30 controller 
provides 1 mA graduated control of an electrolytic suppressor in addition to providing control of 
an  Eluent  Generator  Cartridge  (Dionex  EGC)  and  a  Continuously  Regenerated  Trap  Column 
(Dionex CR-TC). The Dionex SCC-10 suppressor current controller can be used in conjunction 
with the Dionex SRC-1 controller to provide a current output of twelve settings.  

For  optimal  suppressor  performance  it  is  important  to  operate  the  suppressor  at  the 
recommended  current  settings  as recommended  by  Chromeleon  or  as  calculated  from 

Section 

2.6.1.

  It is  highly  recommended  to  set  the  current  setting  for  the  Dionex  ERS  500  or  Dionex 

AERS  500  Carbonate  to  the  exact  calculated  current (within  1 mA).  Older  power  supplies  do 
not  have  the  1  mA  graduated  control. 

Failure  to  set  the  current  accurately  could  reduce 

suppressor performance and life-time
