Course: HTGAA Spring 2026 Lecture (Tues, Apr 7, 2026): Evan Daugharthy, Lindsay Morrison — Advanced Imaging & Measurement Tech Recitation (Wed, Apr 8): Waters Corp Team — Mass spectrometry Author: Fiona (Committed Listener track) At a glance. Mass spectrometry asks a precise quantitative question: did the molecule that came out of the column have the mass we predicted from the sequence? When the answer is yes within a few parts per million, it’s the same molecule. When it isn’t, the difference itself tells you what went wrong. This page builds the logic of intact-protein LC-MS, peptide mapping, and charge detection MS from first principles, with eGFP as the example throughout.Hugoen
