A simple and rapid authentication method is presented for herbal medicine samples using commercially available mid-infrared and near-infrared benchtop spectrometers as well as using a handheld NIR device.
This study explores the use of FT-IR spectroscopy and PLS regression for the authentication of essential oils—wintergreen oil, tea tree oil, rosemary oil, and lemon eucalyptus oil—adulterated with either lemongrass oil or peppermint oil.
The value of combining ATR and transmission spectra for the analysis of polymer laminates is illustrated here through the analysis of a multilayer polymer laminate from a food packaging sample.
Application Notes (Advertising Content)
Combining a high precision FT-IR spectrometer with a long pathlength gas cell provides a powerful tool for analyzing trace levels of contaminants in air and other gas mixtures.
A vibration-resistant FT-IR spectrometer is used to monitor an industrially relevant fermentation process.
