Operating Instructions RF-2000

• Do not apply excessive back pressure to the outlet side of the cell.
• In order to prevent clogging in the flow line, thoroughly clean the flow line before
stop delivery of solvent when the analysis is finished. Especially, when the buffer
solution is used, salts may be crystallized inside flowline. Be sure to clean the flow
line.
• When delivery of the solvent is stopped temporarily, put the tip of the flow line
outlet in the waste liquid in the bottle to prevent clogging of the flow line. This is to
keep inside the flowline being wet.
Important:
When a mobile phase with high insulation, such as hexane,
is used, it is dangerous since static electricity is changed
at the waste liquid bottle. Use a metal liquid bottle for
waste and ground the bottle.
(Refer to section "1.6 Precautions on Static Electricity")
