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

 

B.1.1  Dionex ERS 500 Control for the Dionex DX-120 

The  Dionex  ERS  500,  Dionex  ERS  500e  and  Dionex  ERS  500  Carbonate  are not  compatible 
with the Thermo Scientific Dionex DX-120 instrument. Suppressor control for this instrument is 
only available via the use of a Dionex RFC-10 or Dionex RFC-30 suppressor controller. 

 

Dionex recommends the use of a Dionex RFC-10 or Dionex RFC-30 power supply for the 
Dionex DX-120 instrument. 

 

B.1.2  ERS Control for the CDM-3/PED-2 (Dionex DX-300 Instruments) 

 

The  Dionex  ERS  500,  Dionex  ERS  500e  and  Dionex  ERS  500  Carbonate  are not  compatible 
with the Thermo Scientific Dionex DX-300 instrument. Suppressor control for this instrument is 
only available via the use of a Dionex RFC-10 or Dionex RFC-30 suppressor controller. 

 

Dionex recommends the use of a Dionex RFC-10 or Dionex RFC-30 power supply for the 
Dionex DX-300 instrument. 

B.1.3  ERS Control for the Dionex DX-100 (Model DX 1-03)  

 

The  Dionex  ERS  500,  Dionex  ERS  500e  and  Dionex  ERS  500  Carbonate  are not  compatible 
with the Thermo Scientific Dionex DX-100 instrument. Suppressor control for this instrument is 
only available via the use of a Dionex RFC-10 or Dionex RFC-30 suppressor controller. 

 

Dionex recommends the use of a Dionex RFC-10 or Dionex RFC-30 power supply for the 
Dionex DX-100 instrument. 

 

B.1.4  SRC Controller  

 

 

Thermo Scientific Dionex recommends the Dionex RFC-10 (Item # 060335) for standalone 
control of the Dionex ERS 500, Dionex ERS 500e or Dionex ERS 500 Carbonate in older 
systems. The Dionex RFC-10 provides current at 1 mA intervals for exact current control. 

 

This unit is intended to provide power and control to one Dionex ERS 500 or Dionex ERS 500e 
when the associated detector does not have ERS control integrated into it. 

The SRC-1 Power switch toggles On or Off AC line current to the SRC-1. Current is supplied to 
the Dionex ERS 500 only as long as the SRC-1 is powered on. 

 

 

The Dionex ERS 500 Carbonate is not compatible with the SRC Controller.
