IR Laser Imaging offers higher power density than traditional MIR sources, creating excellent IR spectral data in less time than what is needed for FT-IR acquisition.

Raman 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.

The 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.

Combined 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.

Composite 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.

Raman 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.
