Troubleshooting

 

»

Low or inconsistent flow delivery volume and/or 
superimposed periodic detector signals 

may be due to:

 

»

Not all solvent inlets have been primed. To achieve 
the specified pump performance, ensure that both 
solvent inlets have been primed (see page 6).

 

»

One or more pump check valves are not functioning 
properly. Flush with methanol or a similar solvent 
(see page 20) and check for leaks in the 
tubing or fittings (see “Leaks” on page 32). 
If this does not solve the problem, release the 
check valves as described on page 31.

 

»

Solvent cavitation or degassing during aspiration  
stroke. Possible solutions are: 1. Elevate the solvent 
reservoirs. 2. Lower the ambient temperature. 
3. Sonicate or replace the solvent inlet filters; see 
page 34. 4. Reduce the max aspiration rate for the used 
solvents; see “Administrate Solvents” on page 22.

 

»

The pump does not deliver solvent. 

The problem may be due to:

 

»

No or insufficient solvent in the reservoir(s).  
Refill the solvent reservoir(s) and ensure that both 
solvent inlet lines are submerged in solvent (see 
“Prime the Solvent Inlets” on page 6).

 

»

Stuck pump check valve(s). Flush with methanol 
or a similar solvent; see page 20. If this 
does not solve the problem, release the check 
valves as described on page 31.

 

»

Blockage in solvent line(s). Sonicate or replace the 
solvent inlet filters; see page 34. Straighten or 
replace kinked tubing. If this does not solve the 
problem, flush the entire system with methanol 
or isopropanol at a low flow rate (see page 20).

 

»

Leakage. Check for leaks in the tubing or 
fittings; see “Leaks” on page 32.
