Accurate mass measurements

Accurate mass measurements are done using our FTMS and MALDI-TOF mass spectrometers.

Accurate mass

The typical mass accuracy is within 2 ppm but for many compounds and methods we can achieve accuracy of less than 1 ppm.

Accurate mass can be used for calculation of the elemental composition of a compound, and together with the simulated isotopic pattern it is used for the compound identification.
