Troubleshooting

Symptom	Possible Cause	Corrective Action
High backpressure	Clogged suppressor	Perform cleaning procedure; check for particulates.
High baseline noise	Contamination	Flush with cleaning solution; replace eluent.
Poor peak shape	Insufficient suppression	Check suppressor current; verify regeneration.
No current reading	Electrical connection	Check connector; verify power supply.
Leaks at fittings	Loose connections	Tighten fittings; replace if damaged.

Reset: Power cycle system; reinitialize suppressor module.
