Quantitative Determination of Key Components in the Traditional Chinese Remedy “Red Flower Oil” by FT-IR Spectroscopy

This application note demonstrates that Infrared spectroscopy with ATR sampling can be used to obtain a complete, quantitative determination of the quality of red flower oil within two minutes. A PLS calibration against data obtained from GC measurements allows a very precise determination of methyl salicylate, eugenol and a-pinene.
