Final answer:
In Gas Chromatography, retention time is the timeframe it takes a component of a sample to travel through the column and be detected. Increasing the detector temperature can decrease this retention time, but may risk degradation of some sample components.
Explanation:
Retention time in Gas Chromatography (GC) refers to the time taken for a particular component of a sample to pass through the chromatographic column and be detected by the detector. Specifically, it is the time taken from the injection of the sample to the detection of the component.
If the detector temperature is increased, this would speed up the movement of the sample components through the column, thereby reducing the retention time. The degree of reduction would depend on the specific properties of the sample components and the column. However, it is important to consider that increasing the detector temperature may also increase the risk of degradation of some sensitive components within the sample.

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.
