• 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.
• Green – Lamp energy is sufficient to detect peaks
within typical system limits.
3. Remove the column and insert a bypass tube between the
upper and lower column mounts. A bypass tube
(P/N 209-0165-46) can be found in the accessory kit
shipped with your system.

the bypass tube and into the collection tubes.
Note
Pumping solvent B at a moderate flow rate (25 to 45 mL/min)
overtime will usually solubilize obstructions. Generally, the rec-
ommended solvent is the highest polarity solvent you have
recently used (solvent B).
8. Monitor the Raw Lamp Energy gauge. As the system
pumps solvent, the raw lamp energy should gradually
