Standard spontaneous Raman scattering effect is limited by its sensitivity. Different strategies are set in place to improve the sensitivity and the mapping speed based on different physical phenomena. These approaches resulted in the development of Stimulated Raman Spectroscopy (SRS), Coherent Anti-Stokes Raman Spectroscopy (CARS), Resonant Raman spectroscopy, etc., each of which have advantages and limitations. During this webinar, we will present the concept of these different techniques, and discuss their benefits and concerns.

More and more, Raman microscopy is being used for a wide variety of applications. As a vibrational spectroscopy, it is mainly compared with Infrared absorption. However, the origins of this Raman effect and the information provided by Raman spectroscopy are different than any other. During this webinar, we will present what the Raman effect is and what kind of information can be obtained based on a Raman spectrum.

In vivo skin analysis poses significant challenges due to the complexity of its heterogeneous structure, the variability between individuals, and the need to preserve its integrity during measurements. This webinar demonstrates that the RZ-660 is a reliable and precise tool for molecular skin analysis, opening opportunities for future applications in dermatological research and cosmetic science.

This webinar will explain how detectors and spectrometers work and dig into the notions of efficency, noise, etaloning, numerical aperture and etendue, resolution. It helps understanding the different detectors on the market and their important features. It also reviews the important parameters of a spectrometer depending on the experimental needs.

Raman microscopy is more and more becoming a standard method in many application domains. This transforms Raman microscopy from a high-end technique to one that is widely used. Consequently, it has to come with tips-and-tricks, but also with dedicated tools to support these different applications. These supporting tools can be accessories or software dedicated apps. During this webinar, we detailed the tools and accessories supporting Raman microscopy for specific applications.

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 present how the coupling of plasmonic and Raman effects results to with SERS and TERS and details some applications.

Dive into the powerful world of multivariate data analysis and chemometrics tailored for Raman spectroscopy and Raman imaging. This webinar will showcase how LabSpec 6, our advanced software platform, streamlines complex data interpretation, enabling researchers to extract meaningful insights from multidimensional datasets. Whether you're new to chemometrics or a seasoned professional, this session will guide you through practical approaches to analyzing Raman spectroscopy data, empowering you to make data-driven decisions with confidence.

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 present the role of each component of a Raman microscope and detail their characteristics and limits.

Raman microscopy couples both submicron-scale spatial resolution and high spectral resolution. Thus, achieving the best performances is dependent on a good calibration in both spatial and spectral dimensions. During this webinar, we detailed the different calibration routines applied on Raman microscopy to achieve ideal measurements while remaining compliant with regulations. We also explained how these routines work and why they are important to consider.

Optical microscopy is very common technique for visualization and characterization at the micron scale. Many modalities exist to highlight different features. However, the chemical information is almost always missing. Raman spectroscopy is a complementary technique that can provide chemical information about the sample. During this webinar, we presented how these different microscopy modalities, combined with Raman spectroscopy, make Raman microscopy so powerful.

Raman microscopy provides both molecular and morphological information of the analyzed sample. However, sometimes it is not enough to fully understand a physical or chemical process. That's why the Raman information has to be coupled with complementary information. During this webinar, we will present the different solutions existing to combine Raman with other microscopy techniques in this aim, like SEM, AFM, or all other microscopy techniques.

During this webinar, we will explain impact of processing on Raman spectra and the solutions for Raman image analysis, including multivariate analyzes.

Obtaining a very good Raman spectrum or image is not always very easy. Many parameters must be considered to get the ideal result. During this webinar we will describe the impact of each acquisition parameter and demonstrate how they can be easily optimized, especially in LabSpec6. Thus, Raman spectra and Raman maps acquisitions will become a child’s play for you.

In this webinar, explore how Raman microscopy can be used to identify and characterize microplastics and nanoplastic samples through examples such as hand sanitizer. Plus, gain an overview of the latest HORIBA Scientific solution software: Particle Finder™.

Raman microscopy is an increasingly commonly used technique in analytical labs. However, only few manufacturers can provide high quality instruments that make an appropriate balance between flexibility and ease of use. Several key performance characteristics need to be considered when deciding what makes a good Raman microscope. In this webinar we will demonstrate, how the various instrument characteristics impact on what makes a good Raman microscope.

During this webinar we will show how combining Raman and µ-XRF characterization with this co-localization tool generates valuable information for a range of applications.

Raman microscopy can have the reputation of being difficult to handle. But with all our recent developments...it has become much easier for non-experts to access!
