4.7.2 Weekly check
1. Check whether the instrument pipeline is folded, bent or contaminated. Replace the
deformed pipeline in time to avoid affecting the stability of the flow path. If the pipeline is short,
reset and replace the pipeline in time.
2. Check whether the eluent filter head needs to be cleaned or replaced. The filtering effect
of the contaminated filter head will be greatly weakened. Especially, the filter heads used for
long-term experiments should be checked for pollution. When the filter head is relatively new, it
is pure white. Please clean or replace the filter head in time when it changes color.
3. Turn on the instrument at least once a week and rinse it with ultrapure water for 10
minutes to 20 minutes. The pump head should be back flushed after use.
：
When using aqueous solution as eluent, bacteria are easily generated, thus
affecting the experiment. The contaminated filter head should be cleaned or replaced in
time.
4.7.3 Regular check
1. Regularly replace the reference electrode (about 3 months).
2. Regularly replace the injection needle and pipeline of the automatic sampler.
3. Regularly back flush the pump head.
