• EluGen cartridge leaks
Replace the EluGen cartridge (see Section 9.12
).
• RFIC Eluent Degasser leaks
Replace the RFIC Eluent Degasser (see Section 9.14
).
8.23 No Flow
• DP/SP power is off
Turning off the DP/SP automatically turns off the EG and the suppressor.
Current to the CR-TC is automatically turned on and off when the EG power
is turned on and off.
Check that the power to the DP/SP is turned on. Prime the pump (see
Section 9.3
) and resume operation.
• DP/SP pressure limit tripped
When a system includes an EG, the high pressure limit for the DP/SP is
21 MPa (3000 psi) and the low pressure limit is 1.4 MPa (200 psi). Verify that
the Current Pressure reading on the Control panel is within this range.
NOTE The EluGen cartridge requires at least 14 MPa
(2000 psi) of backpressure for optimal removal of
electrolysis gas from the eluent produced by the
cartridge. A system backpressure of 16 MPa (2300 psi) is
ideal.
• RFIC Eluent Degasser tubing is ruptured
If flow from the EG waste line is normal but there is no flow through the
columns, the tubing assembly inside the RFIC Eluent Degasser has ruptured.
Replace the degasser (see Section 9.14
).
