Sensors provide direct measurement of a specific substance of interest in a sample. For
more information about sensors, refer to Rapidlab 1200 Systems Technology‚ page 1-27.
The electrolyte sensors, Na
reference sensor and use potentiometry. For more information about potentiometry, refer
to Potentiometry‚ page 1-27.
The biosensors (glucose, lactate) and the pO
information about amperometry, refer to Amperometry‚ page 1-33.

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

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.
