  • Formation and Decomposition of Surface Ethoxy Species on Acidic Zeolite Y Studied by the In Situ MAS NMR-UV/Vis Spectroscopy (.pdf)
    spectroscopy allows the identification of species on the working catalyst in more detail, UV/Vis spectroscopy offers the high sensitivity for detecting the formation of aromatic compounds and unsaturated carbenium ions. In this contribution, the first solid-state 13C MAS NMR evidence is presented
  • UV-VIS Spectroscopy of Tannins and Phenols in Red Wine
    Measurement of wine color and tannins involves spectroscopic analysis in the UV and visible region. The test protocols are complex and are hampered by the need make multiple wavelength measurements. A typical spectrophotometer can only make one wavelength measurement at a time. In addition

    spectroscopy and shows the types of transitions which occur in electronic spectra generation. The most common type of spectrometer used in analysis is in the UV/Vis
  • Near IR Spectroscopy in Process Analysis
    NIR has been traditionally viewed by spectroscopists trained in laboratory methods as a less-than-useful spectral region that exists to fill the gap between the UV/VIS and IR regions. NIR peaks are broad, overlapped and much weaker than their IR counterparts. So, why has NIR become so widespread

    of fluorescing is "multidirectional," the detectors are placed perpendicular to the incident light. Thus, unlike UV/Vis, small absorbances (followed by emission) and not the total ouput of the light source are seen against a "dark" background. This allows for detection of trace amounts of analyte.
