Analytical Platform Review: Mass Spectrometers (LC-MS) for Protein Characterization and Quantification
Liquid Chromatography-Mass Sppectoromtery-
It is a powerful analytical technique that combines the resolving power of liquid chromatography with the detection specificity of mass spectrometry. Liquid chromatography (LC) separates the sample components and then introduces them to the mass spectrometer (MS). The MS creates and detects charged ions. The LC/MS data may be used to provide information about the molecular weight, structure, identity, and quantity of specific sample components.Applications of LC-MS
- Proteomics
- Metabolomics
- Protein Identification, Characterization and Quntitation
- Protein Structural Analysis
