Two operating modes (targeted MS(2) and Data-dependent screening) were used for data acquisition.  Even though, data-dependent scan is a faster route towards the potential identification of metabolites, it suffered from its limitation to provide enough data points across the chromatographic peak during the MS(2) cycle in contrast to targeted MS(2).
