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 menbrane) is used to selectivety remove dissolved gasses ; using the characteristics of tne small molecular size of the dissolved gas with high mobility and affinity to the menbrane.

Degassing Capacity
When ion-exchanged water saturated with air at 25deg-C is put through at a flow rate of 3mL/min,
no bubble is observed at the outlet of the apparatus.
(Measured dissolved oxygen level at the outlet : 2ppm at flow rate of 3mL/min)
Internal volume
Max. flow rate
20mL/min for each channel (Eluent: 25deg-C pure water)
External output
An open connector signal is delivered to the external output signal terminal,
When “PRES” and “LEAK” LEDs light.
W71 x D310 x H136 (mm)
Power source
AC 100 to 240 V, 50/60Hz
Power On/Off display
“POWER” LED lights, when the power is supplied.
Status monitoring
“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 pressurein 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.: Cntinuous operation in case og high degree of degassing degassing
