a less frequently accessed chip significantly decreases the chance of those key data to
get corrupted.
In the unlikely event that the flash chip should fail, the analyzer will continue to operate
with just the DOC. However, all configuration information will be lost, requiring the unit
to be recalibrated.
10.4.2. Sensor Module & Sample chamber
Electronically, the M100E sensor module is a group of subassemblies with different tasks:
to detect the intensity of the light from the fluorescence reaction between SO
the sample chamber, to produce a current signal proportional to the intensity of the
fluorescence and to control the temperature of the PMT cooler to ensure the accuracy
and stability of the measurements.

10.4.3. Sample Chamber Heating Circuit

In order to reduce temperature effects, the sample chamber is maintained at a constant
50°C, just above the high end of the instrument's operation temperature range. Two AC
heaters, one embedded into the top of the sample chamber, the other embedded directly
below the reference detector's light trap, provide the heat source. These heaters operate
