Abstract
The invention discloses an analysis system for in-situ electrochemistry-mass spectrometry combination. The analysis system comprises an electrochemical cell, wherein electrolyte is arranged inside theelectrochemical cell; a work electrode, a reference electrode and an auxiliary electrode are arranged in the electrochemical cell; the work electrode is fixed in an inverted mode; a mass spectrometrysample feeding opening is fixed in an overhead mode and is arranged under the work electrode; the distance between the work electrode and the mass spectrometry sample feeding opening is regulated andcontrolled; the mass spectrometry sample feeding opening is arranged below the liquid level of the electrolyte. The analysis system has the advantages that the inverted mode structure of the work electrode and the overhead mode structure of the mass spectrometry sample feeding opening conform to the hydrodynamic principle of volatile products; the product collection is easy. Meanwhile, through the flow speed control of a sampling pump and a sample outlet pump, reaction liquid at the work electrode surface and the electrolyte of the whole electrochemical cell can be timely updated. The whole device can be easily mounted and dismounted. Wide application prospects are realized in the fields of catalysis, energy storage, adsorption, environment and the like.
