Note:
The Program Wizard or SmartStartup Wizard guides you in setting the recommended current for the suppressors. The Wizard supplies a recommended current based on the eluent concentration and flow rate settings. Chromeleon automatically enters the recommended current into the Program and applies that current to the suppressor. To ensure the optimal performance of the suppressor, always accept the recommended current setting.
