Description

technical field [0001] The invention relates to a system for quickly identifying products of molecular ion reaction online in a gaseous environment, in particular to a molecular ion reaction mass spectrometry system and a molecular ion reaction and cleaning method. Background technique [0002] The conventional chemical reaction is the reaction between chemical reagents in the laboratory, which is usually called "wet experiment", which has problems such as large sample volume and difficulty in timely detection and identification of process products. Molecular ion reactions in a gaseous environment can effectively solve these problems, not only using a small amount of reagents, but also quickly and in time to detect intermediate products. However, molecular ion reactions in a gaseous environment require a set of equipment to realize, at least molecular reagents need to be loaded into the system , ion source system, molecular ion reaction vessel and product qualitative and qua...

AI Technical Summary

Problems solved by technology

[0007] However, molecular ion reaction mass spectrometry systems usually use a rectangular ion trap as a container and a mass analyzer. There are several problems: the reagent ions of interest are difficult to obtain, or the amount of reagent ions obtained is very small; reagent molecules and reagent ions may be difficult to generate due to insufficient activity. Reaction; reagent molecules tend to pollute the ion trap, affecting the generation of subsequent reagent ions (due to the existence of reagent molecules, it is difficult to produce ions of interest), thus affecting the subsequent molecular ion reaction results

In addition, cleaning the ion trap is a time-consuming and laborious work, which needs to be undertaken by personnel trained in instrument installation

These problems hinder the widespread application of molecular ion reaction mass spectrometry systems.
