WebJan 19, 2024 · Retention time (RT) is a measure of the time taken for a solute to pass through a chromatography column. It is calculated as the time from injection to detection. The RT for a compound is not fixed as many factors can influence it even if the same GC and column are used. When to use relative retention time and RRT? WebDec 20, 2024 · Any peak with the retention time of 6.5 minutes will be identified as the fourth component. So using RRT will actually shift the component in the processing method, whereas Rel RT Reference will just give you the component’s retention time as compared with another component.
