Figure 9

A graphical representation of retention time adjustment. A target peak (tmdenoted by ยท) to be aligned is moved to new position denoted by (*) after peak alignment. X-axis presents the first retention time and Y-axis presents the second retention time. The dotted grid presents target retention time (t L 1 and t H 1: the closest target RT1 below and above tm, t L 2 and t H 2: the closet target RT2 below and above tm). The solid grid presents reference retention time (r L 1 and r H 1: the corresponding reference RT1 aligned to target RT1, r L 2 and r H 2: the corresponding reference RT2 aligned to target RT2).
