High Resolution MS (HRMS) Low resolution mass spectrometers report m/z values to the nearest whole number. High resolution mass spectrometers measure m/z ratios to four (or more) decimal places. This is valuable because no two molecular formulas have the same exact molecular weight. Exact MWs can be calculated using exact isotope masses. Table 14.1 Thus HRMS is a way to determine chemical formula!
