Detailed information on the maintenance work described below is given in the manual for your instrument.
Aspiration filter: The aspiration filter should be replaced if it is discolored or at least every three months. Contaminated aspiration filters can lead to pressure and baseline fluctuations.
IC pump: The piston, seals, and valves should be serviced at least once a year.
Inline Filter: The Inline Filter should be replaced if the backpressure increases or at least every three months.
Pulsation absorber: Maintenance is not possible. Defective pulsation absorbers must be replaced.
6-way injection valve: If there are problems with the precision, check the installation of the sample loop. More extensive maintenance should be carried out by a service technician.
Suppressor (MSM, MSM-LC, MSM-HC): If the capacity drops or a high backpressure builds up, the Suppressor Module must be regenerated, cleaned, or replaced.
Detector block (conductivity detector): A blocked inlet capillary can be shortened by a few millimeters. Backflushing with the high-pressure pump may also help. Caution: The pressure must be < 5 MPa. The detector block must not be opened under any circumstances.
Detector cell (amperometric detection): The working electrode can be cleaned and polished as described in the manual. The reference electrodes are maintenance-free. The Ag/AgCl reference electrode must be replaced at regular intervals.
