WebJan 1, 2024 · Abstract. High-resolution mass spectrometry (HRMS) can determine the masses of compounds with much greater precision than low-resolution mass spectrometers, with mass differences as low as 0.0001 Da, making it possible to distinguish between compounds based on exact mass rather than integer mass. Traditionally, many … WebHigh-resolution mass spectrometry (HRMS) is a mass spectrometry technique for trace level analysis. HRMS can achieve mass measurement accuracy of 0.001 Da and detect trace quantities (mDa) of elements.
