Section 6 Maintenance
• Red – lamp energy is obstructed to a degree that the
system might not reliably detect peaks. If you
attempt to operate the system, peak collection will be
forced to collect all. This prevents diverting desired
compounds to waste.
• Yellow – lamp energy is partially obstructed and the
peak detector performance might be impaired. The
system can be operated although the absorbance
trace might appear noisy. Yellow might be a normal
indication for systems with flow cell windows stained
by compounds.
• Green – lamp energy is sufficient to detect peaks up
to 2.4 Absorbance Units.
3. Remove the column and insert a bypass tube (P/N
209-0165-76) between the upper and lower column mounts.
4. Set the Flow Rate to 200 mL/min (Figure 6-4).
5. Select Through column for the Valve Position option.
6. Select Next for the Pump into Tube # option. By pumping
into a collection tube, the diverter valve is also cleaned of
any residue during this operation.
7. Click the Prime B button to pump 100% Solvent B through
the bypass tube and into the collection tubes.
