2.2 Inside Front Panel
Grasp the Dionex PDA front cover by the sides and pull it straight off to access
the inside front panel (see
Figure 2-3 ).
•
The flow cell cover protects the cell from dust, ambient light, fluctuations in
ambient temperature, and vibration.
•
The lamp cover enhances the thermal stabilization of the optical bench. The
optical bench is housed in a compartment behind the inside front panel.
•
Because the flow cell is located behind a cover, leaks from the cell tubing
connections will not be apparent immediately. To prevent damage to detector
components, the bottom of the optical bench contains a built-in leak tray. A
sensor in the sump of the leak tray responds to changes in the index of
refraction when wet.
When the leak sensor is activated, it triggers an alarm in the detector, the
ALARM
LED lights (see Figure 2-1 ), and an error message is logged in the
Chromeleon Audit Trail. After fixing the leak and drying the sensor, clear the
ALARM
LED (see Section 4.2 ).
