Shodex Analytical Mobile Phase Degasser

Eluent Degassing Device: DEGASSER ERC-3215alpha, 3415alpha

The ERC-3000alpha series efficiently remove dissolved gases in the eluent.


  • Pressure sensor and leak monitor assure high degree of safety
  • Dead volume is minimized to 7mL/channel
  • Any pump can be used since differential pressure is low
  • Continuous degassing mode aids eluent preparation for high-sensitivity analysis
  • EMC and LVD compliance, with CE marking

(Degassing Principle)
A special synthetic membrane (degassing membrane) is used to selectivity remove dissolved gasses ; using the characteristics of the small molecular size of the dissolved gas with high mobility and affinity to the membrane.

Functional Displays

Power On/Off display “POWER” LED lights, when the power is supplied.
Status monitoring function “READY” LED lights, when the internal pressure in the vacuum chamber is below a predetermined limit.
Pressure monitoring function “PRES” LED lights, when the internal pressure in the vacuum chamber does not reach a predetermined level within a predetermined time.
Leak monitor “LEAK” LED lights, when the liquid leaks in the apparatus.
Self cleaning The vacuum line is cleaned by air suction.
Vacuum pump operation switching function NORM.: Controlled operation in normal run
CONT.: Continuous operation in case of high degree of degassing degassing
