EC-Raman Integrated Raman Microscope

Traditional Raman microscopes often have a large footprint, high cost, and complex operation, which makes them difficult to use in many laboratories and non-specialized research settings. The EC-Raman high-performance Raman microscope addresses these issues with a compact, integrated design that overcomes spatial constraints. It can be easily placed in demanding environments such as glove boxes and integrates capab ilities
for in-situ electrochemical Raman measurement and intelligent particle identification. It provides an advanced yet user-friendly solution for research laboratories and high-quality teaching.

The first integrated microscope to achieve transient electrochemical Raman spectroscopy

JAYITEC was incubated by Xiamen University Jiageng Innovation Laboratory, with core technologies originating from decades of interdisciplinary research in electrochemistry and spectroscopy at the College of Chemistry and Chemical Engineering, Xiamen University. In 2015, the team pioneered Transient Electrochemical Raman technology, opening a new dimension for in-situ electrochemical interface studies. EC-Raman, the first commercialized system based on this technology, integrates 11 proprietary intellectual properties and represents a leading advancement in integrated electrochemical Raman microscopy.

Integrated Architecture - Deep Hardware-Level Integration

EC-Raman integrates three traditionally independent systems — microscopic imaging and scanning, Raman spectroscopy, and electrochemical analysis — into a single integrated platform.
With all optical paths and electronic components built into the main system, EC-Raman eliminates the conventional setup of “three separate instruments + multiple cables + multiple software platforms.” This integrated architecture fundamentally resolves common challenges in external coupling solutions, including inconsistent communication protocols, uncontrollable transmission delays, and disconnected datasets.
Equipped with a patented magnetic electrochemical cell, EC-Raman enables tool-free connection and second-level sample loading, greatly simplifying experimental setup and improving operational efficiency.

Transient Electrochemical Raman Technology: From Static Observation to Dynamic Reaction Tracking

Electrochemical interfaces often involve short-lived intermediates whose formation and transformation occur on millisecond or even microsecond timescales. However, conventional electrochemical Raman approaches typically rely on a “potential stabilization followed by spectral acquisition” workflow, providing only averaged information under steady-state or near-equilibrium conditions. This is similar to capturing a static photograph of a reaction, where critical transient processes remain hidden.
In 2015, the team’s chief scientist pioneered Transient Electrochemical Raman technology and introduced this methodology in the Journal of the American Chemical Society (JACS), overcoming the limitations of conventional steady-state measurements.
By synchronizing Raman acquisition with continuous potential scanning or rapid potential steps, this technology enables real-time tracking of molecular species evolution at electrode interfaces. It directly reveals the formation, transformation, and disappearance of reaction intermediates, providing time-resolved molecular-level insights for studies of electrocatalysis, battery interfaces, corrosion mechanisms, and beyond.
If conventional electrochemical Raman is like taking a photograph, Transient Electrochemical Raman is like recording a video — capturing not only where a reaction starts and ends, but also how it actually happens.

Implementation Approach: Sub-100 ns Hardware Synchronization Between Electrochemical and Raman Signals

Transient Electrochemical Raman demands precise time-domain synchronization between electrochemical excitation and Raman acquisition. 
Hardware Trigger Synchronization
The system’s main control unit simultaneously coordinates the electrochemical module and Raman spectrometer. When the electrochemical excitation signal changes, the control system immediately sends a hardware trigger to initiate Raman acquisition, achieving a synchronization delay ≤ 100 ns.
This near-zero-delay synchronization provides a reliable temporal foundation for capturing millisecond-scale transient Raman responses, enabling accurate observation of dynamic electrochemical processes.
