Offline LC-EC and LC-MS Correlation and Regression. The RTs of six endogenous metabolite standards and the void volumes from both the LC-EC and LC-MS instruments were used to create a linear regression that correlates the RTs between each method. The RTs showed a linear relationship (R2=0.99), and this regression equation was then used to predict where metabolites would be expected between the methods.
