We call the length of time between injection and position of the target compound peak a retention time. On the other hand, the time difference between the peak of an unretained compound and a target compound is called the adjusted retention time. We call the retention time of a compound that is not retained by stationary phase the gas hold-up time.

For a particular compound, the retention time will vary depending on: the boiling point of the compound. A compound which boils at a temperature higher than the column temperature is going to spend nearly all of its time condensed as a liquid at the beginning of the column. So high boiling point means a long retention time.
