How Is Peak Asymmetry Caluclated in Analyst® Software Quantitate Mode?

For research use only. Not for use in diagnostic procedures.

Answer

Peak asymmetry is calculated in Analyst® software Quantitate mode by the following formula:

((Peak end time) - (Retention Time)) / ((Retention Time - (Peak start time)).

Values near 1.0 indicate symmetric peaks, values greater than 1.0 indicate tailing peaks, and values less than 1.0 indicate fronting peaks.
