Column heater/cooler operation
Topic LCI-USG-0139, Last Updated 11/08/2024

This module is a combination conductive heater and cooler.

When the column compartment temperature is set, either directly from the console or within a method, a command is sent to the CHC to switch the compartment heater/cooler engine on or off. On the basis of feedback from the compartment thermistor, the thermoelectric device continues to heat, or cool, until the compartment achieves the specified temperature set point.

Recommendation: When sample and column temperature are important to an application, in addition to specifying explicit temperature set points in the method, specify appropriate temperature limits. Together, these settings ensure that system operation occurs only within the defined limits and that any occurrence of an unacceptable deviation from the set points is flagged by an error message acknowledging the variance.
