Use this retention factor calculator to determine the retention factor (k) from gas holdup time and analyte retention time. This tool helps assess chromatographic retention behavior in capillary GC analysis.

Reference Formula
\[ k = \frac{t_R – t_M}{t_M} \]Before You Go
Ensure that the gas holdup time (t_M) is measured using an unretained compound such as methane or air. An inaccurate dead time will directly distort the calculated retention factor.
For complete chromatographic optimization, consider using this calculator together with resolution and theoretical plates calculations.
The article explaining how this calculator works is available at GC Retention Factor Calculation (k) – Simple and Practical Guide in Gas Chromatography Columns series.
