Agilent G2080AA Retention Time Locking Application Note
This document describes the use of the G2080AA retention time locking (RTL) software tool to ensure consistent retention times when transferring chromatographic methods between different Agilent GC-MSD systems or after routine column maintenance. The study focuses on a derivatized cocaine standard analyzed on systems including the 6890/5972, 6890/5973, and 5890/5972 configurations.
The application details the experimental setup using an Agilent HP-5MS column and helium carrier gas. It presents results showing that retention times could be locked within 0.01 minute across different instruments and after column trimming, allowing a single calibration to be used for multiple systems and facilitating data comparison.
