sensor work with a
reference sensor and use potentiometry. For more information about potentiometry, refer
to
Potentiometry‚ page 1-27.
The biosensors (glucose, lactate) and the pO
2
sensor use amperometry. For more

CO-ox Module
This section applies to the Rapidlab 1245 and 1265 systems.
The Rapidlab 1200 system CO-oximeter measures the concentration of total hemoglobin
and hemoglobin fractions. The CO-ox module contains the following components:
• sample chamber
• sample chamber interface
• polychromator
•pump
Figure 1-22 CO-ox Module
The system measures as the sample flows through the sample chamber. The optics head
directs light through the sample in the sample chamber. The system collects the light at the
other side of the optics head and then the polychromator measures it.
