Biotage Selekt - QR Reader Problems

Troubleshooting
» Low or inconsistent flow delivery volume and/or
superimposed periodic detector signals may be due to:
» Not all four solvent inlets have been primed. To achieve
the specified pump performance, ensure that all
solvent inlets have been primed (see page 7).
» One or more pump check valves are not functioning
properly. Flush with methanol or a similar solvent
(see page 23) 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 32.
» 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 25.
» 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 all
used solvent inlet lines are submerged in solvent
(see “Prime the Solvent Inlets” on page 7).
» Stuck pump check valve(s). Flush with methanol
or a similar solvent; see page 23. If this
does not solve the problem, release the check
valves as described on page 32.
» 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 23).
» Leakage. Check for leaks in the tubing or
fittings; see “Leaks” on page 32.
