Oxygen exact mass
WebWith a high-resolution mass spectrometer it is possible to carry out mass measurements on the molecular ion (or any other ion in the spectrum) to an accuracy of approximately one part in one million. This mass provides the best index for determining ionic formulas. The accurate masses of the ions C 6 H 12+ and C 4 H 4 O 2+ are, for example, 84. ... WebGet an exact fit for your vehicle.
