WebWe have shown that SRM bioanalytical methods using better than unit-mass resolution (Q1 FWHM = 0.2 Th, Q3 FWHM = 0.7 Th) can be developed which are as rugged as unit resolution methods (Q1 FWHM = 0.7 Th, Q3 FWHM = 0.7 Th). The enhanced resolution methods require more attention to detail than unit resolution methods. WebCompared to ion traps or quadrupole mass spectrometers they could provide accurate masses and accurate isotopic abundances together. The same principle can be used for gas chromatography (GC) solutions. Any GC-MS (usually a fast scanning TOF) with accurate masses and accurate isotopic abundances and sufficient resolving power (> 5000, …

Half width at half maximum (HWHM) is half of the FWHM if the function is symmetric. The term full duration at half maximum (FDHM) is preferred when the independent variable is time. FWHM is applied to such phenomena as the duration of pulse waveforms and the spectral width of sources used for … See more In a distribution, full width at half maximum (FWHM) is the difference between the two values of the independent variable at which the dependent variable is equal to half of its maximum value.
