Non-invasive measurements - directly in the process

Advanced process spectrometers are the heart of our Process Analyzers. They have been designed specifically for the online use in process environments. Within the wide variety of available equipment, SPACT is your independent guide to the hardware solution that suits you best. Naturally, for the benefit of our customers, we have entered into alliances with reknowned manufacturers such as Bruker Optics, Kaiser Optical Systems and tec 5.

Mid Infrared (MIR)

MIR spectroscopy detects chemical conversions where polar bonds change. This applies to both organic chemical reactions and many anorganic reactions. Unlike near-infrared (NIR) spectroscopy, MIR spectra contain very specific information, requiring a much lower calibration effort.

Raman

Raman spectroscopy delivers information about non-polar bonds and is thus complementary to MIR-spectroscopy. The information content of Raman spectra is equivalent or even higher than that of MIR spectra. This allows detecting processes that aren't visible with MIR spectroscopy due to low signal strengths.

UV-VIS

UV-VIS spectroscopy is sensitive to material changes that affect coloration. This includes color changes visible to the human eye ("VIS" range) as well as changes in the ultraviolet(UV) range, which is typical for dyes and other colorising agents. The optical components of UV-VIS spectrometers operate on highest technological level and maturity and thus allow the design of extremely robust analyzers.

Near-Infrared (NIR)

NIR spectroscopy is the default technique in process spectroscopy: well-established, requiring less complex hardware compared to other spectroscopic techniques, and sensitive to many physico-chemical properties. Measurements of solids, liquids or heterogeneous samples in transmission or reflexion are possible due to a variety of sampling accessories. For good reasons, NIR spectroscopy is considered the universal tool for many applications.

NMR

Nuclear magnetic resonance (NMR) spectroscopy is the standard method for structure elucidation in chemical synthesis. Recent developments allow future applications of compact permanent magnets in benchtop instruments for close-to-process measurements in a by-pass or autosampler. 1H spectra also allow calibration-free quantitative analyses of mixtures.
