Metabolomics

Metabolomics measures the small molecules a cell or tissue produces, often hundreds at once and across a concentration range of several orders of magnitude, so the work leans harder on the analytical instrument than on any single preparation step. A run stands or falls on separation and detection: chromatography resolving the mixture, a mass spectrometer or NMR identifying what comes off it. Questpair lists 35446 items across the categories this work draws on, from 158 suppliers. Because the output is a comparison between samples rather than a single reading, reproducibility matters more here than peak performance, which shapes what a lab buys at every stage.
