Mass spectrometry is used a wide range of industries. The analytical tool estimate the mass-to-charge ratio (m/z) of molecules in a sample, with data used to determine precise weights and concentrations. Developments and advances continue to expand the mass spectrometry a wide range of industries, including clinical applications and laboratory medicine. Below, we are Discussing. Liquid chromatography-mass spectrometry : Benefits of combining mass spectrometry with the separation capabilities of high-performance liquid chromatography , LC–MS has set a new benchmark for analytical chemistry in clinical applications. Drug testing : Advances in mass spectrometry have made it even harder to detection introducing a new drug detection method called ion mobility-mass spectrometry. Immunoassays : The analytical range and impressive specificity of mass spectrometry makes it a useful immunoassay instrument. Multiple hormones can be identified and determined during the same
