IC System showing zero Ion counts, (0%) on a new EG cartridge. 


All of the reagent-free Ion chromatography systems


  1. Find the latest firmware and update it from the service manager in the software apply a a concentration value on the EG and monitor the current-voltage value in the software command, check the change in the current value when you change the concentration applied values. 
  2. If this still showing zero value, EG control board need to be checked and replaced.


  • System not recognizing the EG cartridge because of its firmware
  • Faulty EG control board/power supply
