13.5.2.1. SAMPLE CHAMBER 
The main electronic components of the sample chamber are the reference detector (refer 
to Section 13.1.4); the UV Lamp (refer to Section 13.1.3) and its electronically operated 
shutter (refer to Section 13.1.6); and the sample chamber heating circuit.

13.5.2.2. 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 
off of the instrument’s main AC power and are controlled by the CPU through a power 
relay on the relay board. A thermistor, also embedded in the bottom of the sample 
chamber, reports the cell’s temperature to the CPU through the thermistor interface 
circuitry of the motherboard.
