MEMS-spectrometer sets new standards in NIR analytic
HiperScan GmbH, the company for high performance near infrared spectrometers is presenting their OEM devices at PittCon 2009, the largest exhibition for analytical chemistry and applied spectroscopy, March 9 – 12, 2009 at Chicago.
An innovative scanning micromirror technology, which has been developed and tested at Fraunhofer Institute for Photonic Microsystems IPMS, Germany, enables a revolution in NIR spectrometry.
The spectrometer SGS1900 is a compact and rugged near infrared spectrometer that uses a new scanning grating technology to avoid any expensive NIR diode array. The flexible OEM device is designed for process and quality control in different industry sectors like food, feed, polymers, recycling, chemical and pharmaceuticals.
The SGS1900 measures one single scan in the spectral range from 1000 nm to 1900 nm in only 10 ms with an excellent signal to noise ratio. Especially at the upper end of the spectral range this includes distinctive absorption bands of many compounds that can be identified or quantified. The analysis of a large number of materials is possible and rather flexible applications can be achieved. Therefore the SGS1900 offers an important advantage compared to spectrometers with limited spectral range up to 1700 nm.
The knowledge about the change of the light when you irradiate meat with a light beam is necessary for the measurement of its wasting level, for example. The determination of polymers at the recycling industry or the analysis of indefinable fluids at the airport operate in the same way. Low-priced and highly flexible handheld analysers can be build and open up totally new application fields. The measurement of the degree of ripeness of fruits and vegetables is only one example for handheld applications.
For more sophisticated applications in process an quality control that require the information about the geometrical shape of the object in addition to the spectral characteristics, so called Hyperspectral Imaging is an emerging technology. A respective system, developed by Fraunhofer IPMS is also shown at PittCon. By use of a micro scanning mirror with special grating produced at Fraunhofer IPMS, a very cost efficient solution for Hyperspectral Imaging has been developed that enables a more widespread use of this technology and opens it for completely new fields of applicaton.
In collaboration with the Fraunhofer Institute for Photonic Microsystems IPMS HiperScan exhibits their revolutionary NIR spectrometers and NIR applications at PittCon 2009, March 9 – 12, 2009, booth 3108.
