WebMass spectrometry is a sensitive technique used to detect, identify and quantitate molecules based on their mass-to-charge ( m/z) ratio. Originally developed almost 100 years ago to measure elemental atomic weights … WebMass cytometry combines the precision of mass spectrometry with the power of flow cytometry by allowing scientists to easily measure 44 different parameters simultaneously without the need for spectral compensation or unmixing. This means scientists can identify 25+ different immune cell subsets and profile cellular activation, exhaustion, and ...
