Abstract
The invention discloses a micro heating platform for measuring a molten salt electriochemistry in-situ Raman spectrum and a sample cell, belonging to the technical field of electrochemical analysis. The micro heating platform comprises a heating platform housing, a hearth, a heating platform cover, uprights and a base, wherein a heating platform housing circulating loop water path is arranged inside the heating platform housing, a sample cell arrangement groove is formed in the top of a hearth main body, bar-shaped grooves are symmetrically formed in the left side and the right side of the sample cell arrangement groove, resistance wire mounting holes are formed in the hearth main body at two sides of each of the bar-shaped grooves and the sample cell arrangement groove, spiral resistance wires are arranged in the resistance wire mounting holes, and the resistance wires and the hearth main body are arranged in an insulating manner; a heating platform cover circulating cooling water path is arranged in a heating platform cover main body, and a microscope lens through hole is formed in the middle of the heating platform cover main body. The sample cell has the structure that a quartz cover is arranged at the top of a crucible; through holes are formed in the upper part of the crucible and correspond to the bar-shaped grooves; if the crucible is made of a conductive material, the crucible can be simultaneously used as a counter electrode, or the counter electrode can be singly arranged in the crucible.
Description
technical field [0001] The invention belongs to the technical field of electrochemical analysis, in particular to a micro-heating stage and a sample cell for electrochemical in-situ Raman spectrum measurement of molten salts. Background technique [0002] In contemporary electrochemistry, the development of spectroelectrochemical technology is very rapid. Electrochemical in situ spectroscopy involves many spectral studies such as ultraviolet and visible spectroscopy, infrared spectroscopy, Raman spectroscopy, electron and ion energy spectroscopy, magnetic resonance spectroscopy, and X-ray spectroscopy. field. In recent years, with the advancement of technologies such as confocal Raman, microscopic Raman, and resonance Raman, as well as the improvement of the performance of Raman spectroscopy instruments (detectors, lasers, etc.), the time resolution, spatial resolution, and detection sensitivity of Raman spectroscopy technology have increased significantly. increase in magn...
