Abstract

The invention relates to a temperature control module, a temperature control system and an ion source device for an ion source. The temperature control module includes: a primary cooling channel for cooling the body of the temperature control module through low-temperature cooling gas; a secondary cooling channel for passing through the interior of the temperature control module and for flowing through the secondary cooling gas; The warm module body is used to deliver the secondary cooling gas to the ion source. The two-stage temperature control scheme adopted in the present invention makes the inlet of the secondary cold zone gas be normal temperature gas, and when exchanging heat with the temperature control module, it can still maintain high airflow stability even under relatively high pressure, thereby Higher precision temperature control stability can be achieved.

Description

technical field [0001] The invention relates to the technical field of mass spectrometry, in particular to a temperature control module, a temperature control system and an ion source device for an ion source. Background technique [0002] Understanding intermolecular interactions at the molecular level has extremely important theoretical significance and application prospects, especially the use of molecular detection techniques to obtain structural information of non-covalent complexes, such as binding type, binding ratio, binding strength, binding site, structure Dynamic changes, etc., will deepen people's understanding of living systems and help improve the ability to regulate non-covalent interactions, so that they can be better applied to fields such as smart materials. [0003] In terms of revealing the nature of non-covalent interactions, mass spectrometry (MS) technology has unique advantages, especially electrospray ionization (ESI), as a soft ionization method, is...
