Whitepaper: Comparison of portable spectroscopy techniques - FTIR NIR and Raman

Walk through the majority of R&D departments and quality laboratories and you will see FTIR, near-infrared (NIR) and Raman spectrometers aplenty. These now ubiquitous instruments are used to support the manufacture and development of a vast range of products of all shapes and sizes and material types from pharmaceuticals to pasta, paint, petroleum and polymer films. A single spectrometer can be...

Determination of coptis chinensis’ quality by FT-NIR spectroscopy

As a kind of traditional Chinese medicinal materials coptis chinensis has a lot of medicinal value and closely related to human health, Widely used in clinical or disease prevention and treatment. So the quality of medicinal coptis chinensis rapid determination is very important. Calibration model for determination of Coptis chinensis’ quality was built by partial least squares and near infrare...

Determination of Physical Properties of Reaction-Injection-Molded Polyurethanes by NIR-FT-Raman Spectroscopy

Determination of total polyphenols content in green tea using FT-NIR spectroscopy and different PLS algorithms.

This paper attempted the feasibility to determine content total polyphenols content in green tea with near infrared (NIR) spectroscopy coupled with an appropriate multivariate calibration method. Partial least squares (PLS), interval PLS (iPLS) and synergy interval PLS (siPLS) algorithms were performed comparatively to calibrate regression model. The number of PLS components and the number of i...
