Raman Chemical Imaging of Disposable Diapers
November 3rd 2016Raman micro-spectroscopy is a powerful tool to identify the chemical nature of organic and inorganic materials with spatially down to about 1 μm chemical images show the distribution of individual components within heterogeneous materials.
Applications of the Oxford OptistatDry Cryostat with the Vertex Series of FT-IR Research Systems
October 12th 2016Bruker Corporation and Oxford Instruments announce the full integration of Oxford’s new OptistatDry cryostat with Bruker’s Vertex series of FTIR spectrometers. The Oxford OptistatDry cryostat can be utilized for characterizing materials without the use of liquid helium.
Failure Analysis of Packaging Materials
February 1st 2016The LUMOS FT-IR microscope is an all-in-one solution with an integrated spectrometer, a high degree of automation, and a dedicated user interface. The innovative motorized attenuated total reflectance (ATR) crystal allows performing the complete measurement procedure fully automated including background and sample measurements. The dedicated OPUS software Wizard guides the user through the whole measurement procedure. For identification of unknown compounds, spectrum search and mixture analysis are applied using the functionality of the OPUS/SEARCH package. Chemical images of the spectral data are generated from univariate and multivariate analysis results.
Identification of Inorganic Filler Materials in Polymers
October 14th 2015Combined investigations in the far and mid infrared region in a single scan can offer great value for the analysis of polymeric materials. With the use of optical components optimized for combined FIR-MIR spectroscopy, consisting of a wide range mid to far IR beamsplitter and detector, the investigation of both spectral regions in single step is possible.
Analysis of Composite Films using FTIR
June 8th 2015Composite films are mainly used for the packaging of food where many requirements have to be met in order to preserve taste and freshness of the product. Packaging needs to prevent water vapor from entering or leaving the packaging. FTIR Microscopy allows for the identification of different materials in composite films and can determine their distributions. Furthermore, defects in polymer matrix can also be localized and identified.
The Use of Raman Spectroscopy in the Pharmaceutical Industry – from Discovery to the Warehouse
April 14th 2015Raman spectroscopy has been utilized in the pharmaceutical community for years. Raman works best for raw material identification, polymorphic studies and high throughput screening. However, many active ingredients exhibit fluorescence precluding the use of Raman. A new hand-held Raman spectrometer is now available for users to analyze samples utilizing new patented fluorescence mitigation methods. This new spectrometer has a wide spectra range, high spectral quality for optimizing the analysis, resulting in virtual elimination of false positive/false negative test results.
