Maintenance and Troubleshooting
4.2.1 Cleaning the 6-Port Micro Valve
In most instances, the only maintenance that is required is cleaning of the valve.
Cleaning the 6-port micro valve can normally be accomplished by flushing all the
lines with an appropriate solvent(s). The selection of the solvent is dependent on
the nature of the sample and the mobile phases that are used. Typically solvents
such as methanol, acetonitrile, methanol/water (80/20) or acetonitrile/water
(80/20) should be used.
Note: Do not disassemble the valve unless the system malfunction is definitely
isolated to the valve.
4.2.2 Cleaning the of the Syringe Drive of the Syringe Pump
No special maintenance is required other than keeping the pump clean and dry.
Use a clean lint free cloth saturated with methanol for cleaning. Lubricate the
guide rods again after cleaning. A bottle of oil is provided.
CAUTION
Caution: It is important to keep the stainless steel guide rods clean. Avoid liquid
spills that may find their way into the electronics.
4.2.3 Lubrication of the Syringe Drive of the Syringe Pump
A small container of grease is provided for periodic lubrication of the lead screw
as well as a bottle of oil for periodic lubrication of the two stainless steel guide
rods.
CAUTION
Caution: It is important to keep these guide rods clean.
