    Answer:

    The detector temperature doesn’t affect retention time

    Explanation:

    Retention time is one of the chromatographic parameters. Is defined as the time of a compound spends from injection to detection.

    A solute in GC is added to the injector where is volatilized. When volatilized, it pass through a column until the detector.

    The detector temperature doesn’t affect retention time. To change retention time you must change injector temperature or column temperature. An increase in column or injector temperature results in a decrease in retention time.
