Overview of the OilExpress 4 System . 53
Spectrometer and FCM Mounting System
The mounting system positions the spectrometer and fluid control module (FCM) on the right
of the autosampler deck at a safe distance from the moving arm, and so that the tubing
between the injection station and the flow cell (which by design is of fixed length) is not
stretched. It also prevents vibrations from the autosampler from affecting the spectrometer.
The FCM and spectrometer are each located on a drip tray, which is resistant to sample and
solvent drips, but any larger spillages should be cleaned up immediately.
For DUO systems, the two FCM and spectrometer modules are stacked to reduce bench
space (Figure 33).

The mounting system can be easily moved away from the side of the autosampler for flow
cell or spectrometer maintenance. Two pins on the mounting system connect with the ports
on the autosampler base. For the OilExpress 4 XL systems, a spacer is required between the
autosampler and the mounting system so that the spectrometer is clear of the moving parts
of the autosampler (Figure 34).
