Raman Microscope for DTU Chemistry

The Technical University of Denmark (DTU) intends to acquire one complete high-resolution confocal Raman microscopy and spectroelectrochemical characterization system, including all associated hardware, software, accessories, installation, commissioning, training, and warranty. The system will support research and education activities within catalysis, electrochemistry, materials science, energy conversion, sustainable fuels, and chemical synthesis. The primary purpose is to enable advanced in situ and operando characterization of functional materials, catalyst surfaces, and catalytic interfaces under realistic operating conditions, including electrochemical environments, elevated temperatures, controlled gas atmospheres, liquid-phase operation, and flow conditions. The instrument shall provide high-sensitivity Raman spectroscopy and microscopy with high spectral and spatial resolution. The system must support characterization of solids, liquids, heterogeneous materials, catalyst surfaces, thin films, nanostructured materials, powders, and solid–liquid and solid–gas interfaces. The equipment shall further enable investigation of reaction intermediates, catalyst transformations, phase transitions, adsorbates, reaction microenvironments, and dynamic processes occurring during electrochemical and catalytic reactions. The system shall include a confocal Raman microscope with automated operation, high-resolution spectroscopic capabilities, motorized sample positioning, automated focusing, Raman mapping and imaging functionality, and support for multiple excitation wavelengths covering the visible and near infrared spectral range, including excitation wavelengths of approximately 532 nm, 633 nm, and 785 nm. The system must be capable of performing both point measurements and spatially resolved Raman imaging of heterogeneous samples with automated data acquisition. The acquisition shall include low-noise detector technology suitable for weak Raman signals, time resolved measurements, and quantitative analysis of both Stokes and anti-Stokes Raman scattering. The system shall provide access to ultra-low-frequency vibrational information (down to 10 cm-1) relevant for studying structural changes, lattice dynamics, catalyst phase transformations, interfacial species, adsorption phenomena, and local temperature effects at catalytic interfaces. The instrument shall further enable simultaneous investigation of chemical composition, structural dynamics, and local thermal phenomena under operating conditions through acquisition of both Stokes and anti-Stokes Raman spectra. The system shall support automated Raman mapping and hyperspectral imaging of heterogeneous samples with micrometre-scale spatial resolution and high positional accuracy. The system must enable investigation of catalyst heterogeneity, dynamic restructuring processes, spatial distributions of reaction intermediates, and structure–activity relationships during operation. The system shall support time-resolved and operando measurements through direct integration be-tween electrochemical instrumentation and the spectroscopic platform, enabling synchronized electrochemical control and Raman data acquisition. The system shall allow simultaneous monitoring of electrochemical parameters and spectroscopic responses during catalytic operation and provide direct correlation between catalyst state, reaction intermediates, local temperature, and electrochemical performance. The equipment shall be suitable for spectroelectrochemical investigations of electro-chemical reactions and interfaces under controlled operating conditions. The acquisition shall further include dedicated spectroelectrochemical accessories, electrochemical cells suitable for operando measurements, flow-compatible accessories, control software, data acquisition and processing software, computer workstation, vibration-isolated installation platform, and all components necessary for full operation of the instrument. The system shall be designed for long-term research use and support future expansion through additional optical components, detectors, excitation sources, analytical modules, environmental cells, and experimental accessories.
