Analytical Methods for Mass Spectrometry-Based Metabolomics Studies

Chapter
First Online:
Part of the Advances in Experimental Medicine and Biology book series (AEMB, volume 1140)

Abstract

The advancement of mass spectrometry-based analytical platform largely facilitates small-molecule metabolomics studies, which allows simultaneously analysis of a large number of metabolites from bio-samples and give a general picture of metabolic changes related to diseases or environmental alteration. Due to the large diversity of cellular metabolites, globally and precisely examining metabolic profile remains the most challenging part in metabolomic experiment. Mass spectrometry coupled with liquid chromatography enhances sensitivity and resolving power of metabolites identification and quantification, as well as versatility of analyzing a wide array of metabolites. In this chapter, we discussed the technical aspects of each step in the workflow of metabolomics studies we aimed to give technical guidelines for metabolomics investigation design and approach.
