  1. In Situ Raman Spectroscopic Measurements Of Metal Oxides Under High Temperature
    6/18/2019

    Transition metal oxides are compounds composed of oxygen bound to transition metals used in various applications such as heterogeneous catalysts. To study the mechanism of the catalytic process as well as monitor and optimize the reaction conditions, multiple analytical methods such as XAS, NMR, and Raman spectroscopy have been investigated. Raman spectroscopy has been widely utilized in in-situ catalytic process monitoring with metal oxides, even achieved multi-technique characterization by combining with other instrumentations.

    6/18/2019

    The BaySpec Nomadic™, a large-format Raman microscope, is an ideal tool for automatic wafer inspection, characterization, and Raman chemical imaging on large samples with a spatial resolution up to 1 µm, and it can accommodate large samples with a size up to 12 inches. In this application note, Raman spectroscopy used as a solution to identify and characterize graphine, with a direct analysis on its structural information.

  3. Introduction To Portable Multi-Platform Raman System For Fuel Analysis
    6/18/2019

    Raman spectroscopy is a non-invasive, highly sensitive technology that quantitatively probes and analyzes chemical compositions and structures without the need for sample preparation. In the past, this technology was not useful for plant-based and petroleum-based products due to their high levels of high level of fluorescence that can overwhelm Raman signals in all visible wavelengths. This application note introduces BaySpec’s transportable Agility™ product line featuring dispersive multi-wavelength Raman spectroscopy technology. Now liquid fuels’ measurements and analysis are simple tasks done in a few seconds, without contacting, or any preparation of the sample.

  4. Non-Destructive Red Wine Measurement With Dispersive 1064 nm Raman Spectroscopy
    6/18/2019

    The combination of improved Raman technology and the technique’s molecular sensitivity have led to a rise in Raman usage for a variety of applications including pharmaceutical, biomedical, industrial, and forensics. There remains, however, a struggle to extract useful Raman spectra from fluorescent and luminescent samples. BaySpec’s new dispersive 1064 nm Raman spectrometers offer users a turn-key solution that combines the speed, sensitivity, and rugged design of traditional dispersive Raman instruments with the fluorescence avoidance of traditional FT-Raman instruments. This application note presents the results of a non-destructive red wine measurement with dispersive 1064 nm Raman spectroscopy to determine its composition and contamination levels.

  5. Using 1064 nm Dispersive Raman Systems For Analysis Of Petroleum Products
    6/18/2019

    Raman spectroscopy is a non-invasive, highly sensitive technology that quantitatively probes and analyzes chemical compositions and structures without the need for sample preparation. In the past, this technology was not useful for petroleum and petroleum-based products due to their high levels of high level of photoluminescence that can overwhelm Raman signals in all visible wavelengths. This issue is now resolved by BaySpec’s line of 1064 nm excitation dispersive Raman systems that offer maximum reduction in fluorescence interference.

  6. Using 1064 nm Dispersive Raman Systems In Biofuel And Plant Research
    6/18/2019

    Raman spectroscopy is a non-invasive, highly sensitive technology that quantitatively probes and analyzes chemical compositions and structures without the need for sample preparation. In the past, this technology was not useful for plant-based samples due to their high levels of photosynthetic pigments as the fluorescent backgrounds can overwhelm Raman signals in all visible wavelengths. This issue is now resolved by BaySpec’s line of 1064 nm excitation dispersive Raman systems that offer maximum reduction in fluorescence interference.

  7. How To Make A Tissue Raman Measurement At 1064 nm
    6/18/2019

    The combination of improved Raman technology and the technique’s molecular sensitivity have led to a rise in Raman usage for a variety of applications including pharmaceutical, biomedical, industrial, and forensics. There remains, however, a struggle to extract useful Raman spectra from fluorescent and luminescent samples. For those users who require longer wavelengths such as 1064 nm, the only available option has been FT-Raman. Now, BaySpec’s new dispersive 1064 nm Raman spectrometers offer users a turn-key solution that combines the speed, sensitivity, and rugged design of traditional dispersive Raman instruments with the fluorescence avoidance of traditional FT-Raman instruments.
