· The In-Situ Microelectrochemical Raman Spectrometer integrates a Raman spectrometer, potentiostat, microscope system, and laptop, providing a compact and efficient experimental setup. This system seamlessly combines the potentiostat and Raman spectrometer with a unified power button and power supply, packaging all essential components—Raman spectrometer, potentiostat, and microscope system—into a single unit. All cables, fiber optics, and power connections are neatly concealed within the device or strategically routed along well-designed paths. This integrated design significantly enhances experimental efficiency by ensuring stable signal transmission while minimizing cluttered or cumbersome external wiring, which could otherwise introduce operational errors. The microscope module features a U-shaped movable stage with a wiring switch, optimizing the loading process of the Raman electrochemical cell and reducing the complexity of wire clamping, thereby streamlining sample handling and enhancing user convenience. By combining electrochemical testing with Raman spectroscopic analysis, this in-situ spectrometer enables real-time, non-destructive monitoring of molecular structural and property changes during electrochemical reactions. This technology not only improves experimental accuracy and sensitivity but also expands the scope of research, making it a powerful tool for scientific investigations and technological applications across various fields. Oceanhood’s Raman three-channel module supports multi-wavelength Raman spectroscopy at any three selectable excitation wavelengths, such as 532 nm, 633 nm, 785 nm, 830 nm, and 1064 nm. Equipped with an optical switching system, the module allows for seamless wavelength selection via software control, enabling rapid excitation switching and superimposed Raman spectra analysis for comparative studies. Additionally, the module's plug-and-play probe facilitates easy adaptation for detecting non-conventional samples, enhancing its versatility for diverse applications.
