Environmental research

Environmental research is perfectly supported with Bruker AXS wavelength dispersive X-ray fluorescence spectrometers (WDXRF) S8 TIGER. Accurate and precise determination of hazardous elements down to the sub-ppm level, reliable identification of elements due to high spectral resolution, high analytical performance even for light elements: The TIGER are perfectly suited for these analytical tasks.

The standardless calibration of SPECTRA^plus provides results for every kind of sample and supports therefore all kind of applications. In combination with PETRO-QUANT both wavelength dispersive X-ray fluorescence spectrometers (WDXRF) are dedicated for the determination of traces in hydrocarbon matrices like waste oil, pet coke, used polymers,… Reliable trace analysis from the very beginning.

The highest performance of gas analysis is provided by IFS 125 Series FT-IR Spectrometers with outstanding resolution and broad spectral range. The mobile version IFS 125/M dedicated to gas phase absorption studies is widely used for atmospheric research.

Bruker Optics remote sensing systems offer the capability of automated detection, identification and quantification of chemical gas clouds, liquids and surfaces of interest. A wide range of applications is covered, featuring atmospheric and environmental observation, monitoring of air quality and surveillance of industrial or natural sites such as volcanoes. Emissions can be measured or leakages can be detected and visualized immediately by automated remote monitoring from distances up to several kilometers.

The SIGIS 2 is an ultra-low noise scanning imaging system that is employed frequently in rough environments by emergency response forces as well as by researchers. It is capable of remote identification, visualization and quantification of airborne chemicals.The Hyperspectral Imaging System HI 90 features a detector array for spatially resolved spectral images “in a single shot”. Its outstanding actively aligned interferometer achieves the highest signal-to-noise ratios.The EM 27 is a high-precision automated infrared detection system for the real-time remote sensing of compounds in the atmosphere.The OPS completes the series of systems as a compact, versatile and rugged air monitoring system, designed to detect and measure a wide range of compounds simultaneously using actively modulated infrared radiation in an open path measurement setup.

FTIR microscopy has established itself as the standard method for the analysis of microplastics particles; it can be applied universally and enables a secure identification of all polymer types. Mapping measurements or FPA imaging allow determining thousands of microplastics particles in a fully automated manner.

Total Reflection X-ray Fluorescence (TXRF) analysis allows rapid detection of ultra trace elements down to sub-ppb (µg/l) concentrations. TXRF is well established at universities and environmental research centers for numerous applications like:

• Studies of metal accumulation in biofilms and plankton as longterm indicator for pollution.
• Investigation of entry, distribution and accumulation of nanoparticles.
• Monitoring of "new" element compositions in modern technical products (Tl, rare earth elements)
• (Longterm) studies identifying correlations between metal contanimations and diseases like Parkinson or Alzheimer.
• Aerosol analysis after short-term impactor sampling.

While the advanced TXRF spectrometer S4 T-STAR provides superior performance in the laboratory, the S2 PICOFOX is a compact spectrometer dedicated for field analysis onsite.
