1 The ACQUITY Refractive Index Detector

Temperature control

The detector oven, which controls the temperature of the flow cell, has a
temperature-setting range of 30 to 55 °C, settable to ±0.1 °C. The detector flow
cell temperature reading is accessible via the console or control panel.
The automatically resettable thermal limit switch protects the oven
temperature from raising above the set point, cutting power to the heater
when the thermal limit is exceeded, and displaying an error message. The
switch resets when the oven temperature cools to a safe operating level.
A low ambient temperature can prevent the detector oven from

attaining its set point.
Thermal equilibrium
Allow the detector to reach thermal equilibrium before using it. Under typical
operating conditions, the detector reaches equilibrium within a few hours,
depending on the internal, column, and ambient temperatures.
Recommendation:
set the recycle valve to the recycle position.
