This document introduces Agilent MSD Productivity ChemStation G1701 and G1710 EasyID resolution, tailing, and degradation
This document describes the calculation methods used by the EasyID feature within the Agilent MSD Productivity ChemStation G1701 and G1710. EasyID is a utility designed to update retention times in a quantitation database on a compound-by-compound basis.
The guide details three specific evaluations: Resolution, which calculates peak separation based on EPA method 8280B requirements; Tailing, which measures peak symmetry using an asymmetry factor calculated at 10% of peak height; and Degradation, which determines the percentage area ratio between a primary peak and its degradation product.
The % valley must be at or below 25%.
It uses the Asymmetry factor calculation, not the common USP System Suitability method.
It is calculated as a percent area ratio of the degradation peak to the primary peak.
