Temperature control can be enabled for sample compartment thermostatting. Circulating air is used to cool or heat the sample compartment to the selected temperature, thus allowing precise equalization of the sample temperature.
To achieve an optimum thermostatting performance, keep the front doors of the autosampler closed during sample analysis. Open the front doors only if required, for example to load the autosampler with sample containers.
Sample compartment thermostatting provides a temperature range of +4 °C to +40 °C. Sample cooling is possible to max. 23 K below ambient temperature.
Depending on the ambient humidity, condensation liquid may occur during sample cooling. A drain pump (peristaltic pump) in the autosampler actively removes any occurring condensation liquid from the sample compartment.
The autosampler is equipped with an insulation cover covering the sample loop. This cover protects the interior components from high humidity and extensive condensation when thermostatting the sample compartment. If the cover is not installed properly, thermostatting cannot be enabled or will be turned off automatically.
