Section 6 Maintenance

6-7

• 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.
