Introduction to mass spectrometry data analysis

Mass spectrometry (MS) is an analytical technology that measures the mass-to-charge ratio (m/z) of one or more molecules present within a sample and determines their relative abundance. Mass spectrometry is pervasive within life sciences to detect, identify and quantify compounds within a sample and elucidate the structure or chemical properties of certain molecules. The technology involves ionizing the sample and then stratifying the generated ions based on mass-to-charge ratio to generate a mass spectrum, which is done using a mass spectrometer. In this introductory post, we will briefly discuss how mass spectrometry works and point out some intricacies of MS data.
