The process of finding at least one target molecule in a sample by mass spectrometry.

摘要

The process of finding at least one target molecule in a sample by espextrometria mass.The present invention relates to a process for the detection of at least one target molecule in a sample by mass spectrometry, in which: (a) Ioniza - if the molecules of the sample, (b) is carried out n times the steps (I) and (II) the following, n being equal to 0, 1, 2, 3 or 4. (I) is selected as a function of the Target molecule in a mass analyzer, at least one ion obtained in the previous stage.And (II) to disintegrate the ion well selected, in a cell cluster (c) is connected, a mass analyzer, at least two different ions obtained in step a) when n is zero, in step (b) when n is other than zero, the at least two ions thus stuck with a relationship The mass m / Z on load characteristic of the target molecule.(d) ejects the mass analyzer is the characteristic that trapped ions, and (E) detects if the ions are ejected through a detection device. The process of the invention is characterized by the fact that the characteristic ions are ejected simultaneously in the stage (d) and detected at the same time in step (E).
