Maintenance and Troubleshooting . 97
CAUTION
Ensure that any cleaning solutions will not damage the ZnSe windows.
Also ensure that they are compatible with the materials used in the
OilExpress 4 system fluid path. Refer to
Appendix 4: Fluid Path Materials
on page 149.
Never use strong acids or bases, or oxygen-containing solvents such as
aldehydes, ketones or ethers, with the system without first checking
compatibility, as these liquids may cause immediate and severe damage.
Ethyl and isopropyl alcohol may be used safely.
Removing and Installing the Flow Cell
You may want to remove the flow cell for disassembly and cleaning, or to install another cell.
Ensure that you wear appropriate protective gloves when handling fluid lines that may
contain harmful materials.
WARNING
Take care not to touch the zinc selenide (ZnSe) windows when handling
the flow cell, or wear protective gloves. Zinc selenide is toxic by
ingestion. Avoid contact with skin or eyes.
1. Ensure that the flow cell is empty.
If required, use the
Flush
option on the Autosampler Control screen to flush and dry
the flow cell.
2. Exit OilExpress 4 software.
3. Disconnect the autosampler, spectrometer(s) and FCM(s) from the mains power supply.
4. Disconnect the liquid presence sensor(s) from the rear of the FCM(s).
Refer to Figure 30 on page 50 for details of the connections on the FCM.
5. If you have a DUO system and want to replace the lower flow cell, push the
spectrometer and FCM stacking system away from the autosampler, and then follow the
instructions from Step 5 in
Removing the Sample Shuttle
on page 122 to remove the
sample shuttle from the lower spectrometer.
NOTE: You will need to disconnect both flow cells from the injection station first.
