Microplastics are becoming the 21st century environmental scourge. To control it, more and more regulations are being set in all countries worldwide to monitor the amount of microparticles released in the environment. Thus, some techniques have been identified as reference methods: Pyrolysis GC-MS, Infrared microscopy, and Raman microscopy. This last one provides the best combination of information in both morphological and chemical characterization of each particle down to the micron.
During this webinar, we will present how Raman microscopy is becoming the best reference method for microplastics characterization.

Raman spectroscopy is a good technique for chemical and physical characterization of materials, but suffers from a few limitations like a lack of sensitivity, or its micron scale resolution. Since the 1970s, the coupling of the plasmonic effect with Raman is more and more being used to overcome these limits. This phenomena association results in two enhanced Raman spectroscopies called SERS and TERS, respectively associated to Surface and Tip origins.
During this webinar, we will present how the coupling of plasmonic and Raman effects results to with SERS and TERS and details some applications.

With the global energetic transition and the move from thermic to electric cars, the improvement of battery becomes crucial. With that development, the analytical techniques used must be also adapted and developed to understand the physical and chemical processes occurring at the electrodes and electrolyte levels. Thus, Raman microscopy is an ideal method as it provides physical and chemical properties of materials in a non-invasive approach.

During this webinar, we will present how Raman microscopy can be applied for battery characterization, and for fuel cells, the future of batteries.

Raman microscopy is the combination of the Raman effect and optical microscopy. A Raman microscope is the association of multiple components where each of them is playing a specific role to achieve highly resolved and sensitive measurements.
During this webinar, we will present the role of each component of a Raman microscope and detail their characteristics and limits.

Particulate matter poses a growing threat to air quality and public health. To effectively understand the effects and assess the hazardousness of particles, it is necessary to study them on a molecular level. Raman spectroscopy emerges as an effective method for revealing the chemical composition of airborne particles at the microscopic scale.

In this article, we present the combination of Raman spectroscopy, Photoluminescence and SEM-CL techniques, where the instruments weren’t physically connected. Smart nanostructured materials require a comprehensive understanding of their morphology, elemental and chemical composition. nanoGPS Suite solution allows a colocalized combination of a variety of microscopy techniques, providing a full characterization of nanostructured materials and a precise superimposition of the results obtained.

We all consume or have all consumed sugary drinks at least once. Sugar content of those drinks must be regulated. Also, to avoid those properties of sugar, it has been replaced by sweeteners. These have lower sweetness than natural sugars. Whether it is sugar or sweetener, their content just be controlled. Here, we demonstrate that Raman spectroscopy is one solution to identify and evaluate sugar/sweetener concentrations in a quality control process.

Disinfecting your hands with hydroalcoholic gel has become a daily practice. In the meanwhile, 70° alcohol has been used for even longer to disinfect wounds. But, to remain efficient, the alcohol concentration of these products must not be below a defined threshold and must be controlled. This application note demonstrates how to evaluate alcohol concentrations in a quality control process with Raman.

Multilayer polymer films, composed of different materials, are used in a variety of industrial applications. The analysis of these multilayers is important to support, especially for safety and performances control. Here, we use Raman microscopy by cross-section analysis and confocal depth profiling to investigate the chemical composition of two multilayers films.
