6.4.2 Quick Cleaning when
Recommended
When the lamp energy is lower than normal, the system will rec-
ommend flow cell cleaning (Figure 6-3) before starting a sepa-
ration run.
When the system displays this message you can:
• Cancel Run (recommended) – Click the C
ANCEL
R
UN
button so you can perform a quick cleaning described in
the following steps.
• Continue Collect All – Click this button to ignore the
message. Because the peak detection operation might be
impaired, the system automatically collects all fluids to
avoid diverting compounds of interest to waste.
• Help – Click this button to display the flow cell cleaning
on-line help topic.
To perform a quick cleaning:
1. After clicking the C
ANCEL
R
UN
button, select the
T

>M
ANUAL
C

menu option.
2. From the M

C
ONTROL
window, note the Raw Lamp
Energy level at 254 nm. The Raw Lamp Energy gauge has
two ranges: red and green. (Figure 6-3),
Figure 6-3 Raw lamp energy gauge
• 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 union between the tubing.
4. Set the Flow Rate to 40 mL/min (Figure 6-4).
