Baseline noise can originate from many factors. To minimize the baseline noise, observe the following:
The quality of the mobile phase has a major impact on the performance of the detector. Only use mobile phases of the highest quality available. Keep impurities and contaminants to a minimum. Observe the mobile phase guidelines in this manual. See Mobile Phase Guidelines for the Detector.
Flush the system modules at regular intervals to remove any non-volatile residues from the mobile phase, if applicable.
Follow the maintenance schedules to keep the system modules in optimum performance state.
Keep the supplied gas in optimum quality for the detector.
