Table 2.

Reproducibility of the G2 (maltose) peak of the pre-labeled malto-oligomer ladder by sites. The table contains the mean values obtained from summarizing up 6 consecutive injections carried out by each site. No outlier analysis was performed on the data set before calculating the overall means. (USP: United States Pharmacopeial Convention)
