Method of analysis time of flight in tandem and analysis apparatus by application

摘要

The present invention relates to a method of analysis time of flight in tandem, including: - a step of interaction of a precursor with a target (5), providing at least of the products charged and / or neutral products, - a step of acceleration of the precursors before the interaction in order to allow the detection of the neutral products, - a step of detecting a detector (10), the neutral products and products charged having, for each precursor, the following stages: • start at the arrival on the detector (10) of the first product of the interaction, an acquisition window covering the instants of arrival of the whole or part of the products resulting from the interaction, digitize in the acquisition window (16) at least the time of arrival of the various products resulting from the interaction of said precursor, leading to a set of numbers, labelled the assembly of the numbers as an event, the recording at least a portion of the event, - a step of analysis of events recorded in order to characterize the precursors and / or the target (5) with the help of physical magnitudes.
