Method for determining the maximum mass peak in mass spectrometry

摘要

A fast method for determining molecular mass using mass spectrometry has the following steps: specifying a first adjusting value (M1) of the mass spectrometer, recording the associated signal amplitude (A1), specifying a second adjusting value (M2) which is different to the first, measuring the associated second signal amplitude (A2), specifying a third adjusting value (M3) which is different to the first (M1) and the second (M2) adjusting value, measuring the associated third signal amplitude (A3), determining a quadratic function containing the measured amplitude values as y-values and the specified adjusting values as x-values, determining the maximum of the quadratic function, wherein the searched adjusting value is determined from the x-value of the maximum.

1. A method for determining a molecular mass with the aid of mass spectroscopy, said method comprising the steps of:
predefining a first set value (M1) of the mass spectrometer, capturing the associated signal amplitude (A1), predefining a second set value (M2) differing from the first set value, measuring the associated second signal amplitude (A2), predefining a third set value (M3) differing from the first (M1) and the second (M2) set value, measuring the associated third signal amplitude (A3), obtaining a quadratic function containing the measured amplitude values as y-values and the predefined set values as x-values, determining the maximum of the quadratic function, the searched set value for the molecular mass being determined from the x-value of said maximum.
