Relative Retention : SHIMADZU (Shimadzu Corporation)
Since absolute retention times are affected by many operation parameters, retention parameters less dependent on column dimension and analysis conditions may be desired. Such parameters are expressed by the relative relation of adjustable retention time between the standard sample and unknown sample: relative retention and retention index.

What is Retention Time? - Definition from WorkplaceTesting
In chromatography, retention time (RT) is the interval between the injection of a sample and the detection of substances in that sample. It's the time required for the solute to pass through a chromatographic column. It is the time that elapses after an injection of the sample for the analyte peak to reach the detector. Advertisement

How Long Does It Take for a Kiln to Cool Down? - The Long Wait
Jul 15, 2022The time it takes for a kiln to cool down depends on a few factors. Some of these are the final cone temperature and the size of the kiln. However, the rule of thumb is that cooling the kiln takes at least as long as firing the pottery. So, if it takes 12 hours to reach your target temperature, it takes 12 hours for the kiln to cool.

Why is my LC Retention Time Shifting? - Restek
If all peaks are dramatically shifted to an early retention time, coming out together at or near the void volume, the issue is likely phase dewetting, or what we used to call phase collapse. This is caused by an attempt to use a mobile phase that is more than 95% water/aqueous with a column that is not aqueous compatible.
