Mounting cell holders
The cell holders are pushed onto the adapter plates on the front sample chamber wall
with the guide, thus positioning them near the receivers.

Inserting the cell in the cell
holder
The optical surfaces of the cell (bare surfaces with plastic cells) must be vertical to the
measuring or reference beam path. The layer thickness is a decisive factor for the ab-
sorption measurement. It is therefore important to place all samples (sample and refer-
ence) in the same position and orientation for a measurement. Avoid wedge or angle er-
rors or parallel misalignments of the beam which could cause measuring errors.

Fill the cell at least 20 mm high with analyte.

Insert the cell to be flush against the contact surface of the cell holder (arrow in im-
age below).
