Description

technical field [0001] The invention relates to a flow tube reactor, in particular to a temperature-controllable miniature continuous flow tube reactor. Background technique [0002] The gas-phase cluster reaction device usually includes three functional parts: cluster generation device, cluster reaction device and ion detection device. With the development of the field of cluster chemistry, cluster reaction devices (reaction collision cell, ion trap, selective ion flow tube and multi-ion laminar flow reaction tube, etc.) provide a wealth of information for the study of the reactivity of metal clusters. Especially in the past few decades, the development of ion trap and flow tube reactor technology has dominated the research progress of cluster chemistry. [0003] The length of the traditional flow tube is too long (generally about 1m), which leads to two main problems: [0004] First, the metastable substances generated by the cluster generation device may be agglomerated...

AI Technical Summary

Problems solved by technology

[0005] Second, because the flow tube is too long, the ion current of the product detected by the ion detection device is seriously attenuated, so the signal of the detected product is very weak, which affects further research and analysis

Secondly, since the generation of different cluster ions is accompanied by the change of buffer gas temperature, the uncertainty factor of "temperature" is increased in the study of cluster reactivity in traditional flow tubes, resulting in inaccurate results.
