CAUTION

• For the flow path of eluant of this instrument, Fluorocarbon
polymers, stainless steel (SUS316), ceramics, ruby, sapphire,
quartz are used. Do not use solvents that corrode these
materials. Use only solvents specified in the instruction
manual.
• Before starting operation, check reagent volume without fail.
• Use the pressure limiter function of Pump so that pumping
will stop automatically when liquid leakage occurs.
• When liquid leaks from the flow path system even a little,
loosen the joints, wash them with water, tighten them. Wipe
of the water completely.
• Check the flow paths that can be seen for leakage every day.
About leakage in Reaction device, check at least once per
week. In this case, make Reaction device Off.
• When liquid leaks from Pump Seal unit, tighten Pump Seal
fixing nut, or replace Seal regularly.
• Collect waste solution and dispose of it following regulations
or laws of water turbidity prevention or about sewage.
Improper disposal may cause environmental pollution. A
breach of regulations or laws will be punished.
• To secure reliability of analysis data, measure standard
samples every day to monitor that the instrument is running
normally. Especially manage peak size (area, height) and
retention time of each ingredient. If there is an ingredient
whose retention time is delayed very much, and the peak
cannot be identified, check liquid leakage.
