•
Trapped gases
Release any trapped gases in the cell by loosening the lines to and from the
cell and then retightening them. Also loosen and retighten the fittings to and
from the suppressor eluent ports.
•
Pump not properly primed
Prime the pump (see Section 3.6 ).
•
Contaminated or incorrect eluent and/or regenerant
Remake the eluent (see Section 3.4 ) and regenerant (see Section 3.5 ).
•
Rapid changes in ambient temperature
If the ambient temperature does not meet the specification of 10 to 35 °C (50
to 95 °F), verify that air conditioning and heating vents are directed away
from the Dionex Easion and that the Dionex Easion front door is closed.
•
Insufficient conductivity cell backpressure
Verify that the correct backpressure coils are installed between the cell outlet
and the regenerant bottle inlet. For connection instructions, refer to the
Dionex Easion installation instructions.
Standard bore systems: Use one or two of the black backpressure coils
(P/N 045877) provided in the Dionex Easion Ship Kit (P/N 067768).
Microbore systems: Use one or two of the red backpressure coils
(P/N 045878) provided in the Microbore Tubing Kit (P/N 052324).
•
Insufficient system equilibration following changes to operating
parameters; especially apparent when operating at high sensitivities
Allow a longer system equilibration time (up to 3 hours) before starting to
inject samples.
