Abstract
Background: Tandem of Liquid Chromatography (LC) coupled to Mass Spectrometry (MS) is a widely used analytical technique on metabolomics. LC is used to properly separate the chemical constituents of the body fluid by their affinities toward a packed column while MS identifies the masses through magnetic deflection and measures their relative presence in the sample in terms of intensity. Among others, equipment aging contributes to a background intensity baseline that must be removed motivating...
