Calculate Relative Retention Time (RRT)



Formula

The formula to calculate Relative Retention Time (RRT) is:

\[ \text{RRT} = \frac{\text{Ta}}{\text{Tr}} \]

Where:

What is Relative Retention Time (RRT)?

Relative Retention Time (RRT) is a measure used in chromatography to compare the retention time of an analyte with that of a reference compound. It helps in identifying and quantifying substances in a sample by providing a relative measure of how long each component stays in the chromatographic column compared to a known reference.

Example Calculation

Let's consider an example:

Using the formula to calculate Relative Retention Time:

\[ \text{RRT} = \frac{12.5}{10.0} = 1.25 \]

This means that the Relative Retention Time for this analyte is 1.25.
