Combining Imaging and Spectroscopy: Solving Problems with NIR Chemical Imaging
Infrared Microscopy Historically near-infrared (NIR) spectroscopy has enjoyed significant success as the industrial ‘cousin’ of the mid-infrared FTIR spectrometer. Most NIR spectrometers are significantly more rugged than their MIR counterparts, and are therefore suited for use as a QA/QC tool. Sample preparation is trivial or non-existent for most solid-state or liquid samples and data collect...
متن کاملNIR TIME LINE NIR Spectroscopy : Doing
Herschel used thermometers to determine the heating effect of the sun's rays. He observed elevated temperatures " beyond the red. " Birth's classical diffuse reflectance experiment: All bottles contain same size glass particles. Media surrounding particles: (A) air, (B) water and (C) mineral oil. 1666—Newton disperses white light into colors 1668—Mariotte finds heat disappears when glass insert...
متن کاملSystematization method for distinguishing plastic groups by using NIR spectroscopy.
A systematic classification method for polymers is not yet available in case of using near infrared spectra (NIR). That is why we have been searching for a systematic method. Because raw NIR spectra usually have few obvious peaks, NIR spectra have been pretreated by 2nd derivation for taking well modulated spectra. After the pretreatment, we applied classification and regression trees (CART) to...
متن کاملMeasurement of soil attributes using NIR spectroscopy : A review
Soil fertilizer management is important to adjust the soil fertility by supplying fertilizers at optimum level to achieve maximum yield at minimum environmental risks. Precision agriculture demands to develop better cost and time efficient methodologies for analysis of soil properties. Besides conventional techniques, sometimes spectroscopy is more accurate, fast, non-destructive and inexpensiv...
متن کاملNIR-spectroscopy for bioprocess monitoring & control
Introduction The Quality by Design (QbD) approach shows significant benefit in classical pharmaceutical industry and is now on the cusp to a stronger influence on biopharmaceutical applications. Monitoring the critical process parameters (CPP) applying process analytical technologies (PAT) during biotechnological cell cultivations is of high importance in order to maintain a high efficiency and...
