WebMay 18, 2024 · This accurate mass measurement, along with the pattern of isotopes, allows the exact chemical composition of small chemicals to be deduced with high confidence and even narrows down the elemental composition of biological molecules to a small range of potential formulas. WebHigh-resolution mass spectrometry (HRMS), which enables accurate mass measurement at high resolving power, has recently evolved to the stage that is rapidly causing a shift from unit-resolution, quadrupole-dominated instrumentation. The main HRMS techniques today are time-of-flight mass spectrometry and Orbitrap Fourier-transform mass spectrometry.
