In situ Raman spectroscopy test chamber for gas flow

1. Product use

1) Widely used in all kinds of lithium air battery cathode; In-situ Raman spectroscopy study on electrochemistry of anode materials for sodium air batteries and zinc-air cathode materials

2) The mold is not only suitable for in-situ Raman characterization in charge and discharge process, but also can test phase transition studies in cyclic voltammetry and linear sweep voltammetry

3) The mold can carry out continuous spectrum dynamic monitoring in electrochemical reaction, which is suitable for the study of chemical reaction system under atmosphere environment, and is also suitable for continuous in-situ monitoring of gas-solid multiphase reaction samples

4) The mold can be expanded to perform Raman imaging studies on the electrode surface

5) With standard gas interface and good air tightness, Raman spectrum can be extended for multilevel combined use with mass spectrometry, gas chromatography and other equipment
