58 . High-Performance Lambda Spectrometers Hardware Guide
To install the single-cell holder in the sample compartment:
1. Orientate the holder so that the word LAMBDA is toward the front of the sample
compartment (see Figure 27).
2. Lower the holder so that the two locating holes slip onto the two studs on the two
locating pins on the plinth in the sample compartment.
The cell holder fits one way round only.

3. Move the milled posts a little to locate the threaded holes in the baseplate and then
tighten the milled posts.
You can lead tubes and connecting cables for accessories into the sample compartment
through either the tube ports, located at the front of the sample compartment, or the
opening located at the left rear of the sample compartment, under the cover plate.
When not in use, you should always insert the caps into the tube ports and keep the
cover plate fixed in place.
The cover plate is fixed in place by a retaining screw.
Aligning the Single-Cell Holder
To carry out the coarse alignment of the single-cell holder:
1. Open the sample compartment cover.
2. Fill the cells with a low-absorbing solvent (deionized water or ethanol).
3. Insert one cell into the sample-cell holder and one into the reference-cell holder.
Make certain that the cell is pushed down fully.
NOTE: The alignment procedure is for a given cell in a given holder. After alignment, the cell
should always be used in the same holder.
