Herbal Materials and Natural Foods Analysis with Handheld Raman

In the past identification methods have relied on time-consuming, laboratory test methods. In recent years handheld Raman has been shown to be a valuable tool for quick identifi cation of raw materials in regulated industries. With the advent of a portable, long wavelength 1064nm analyzer, many materials that cannot be measured using handheld Raman with 785nm excitation is now possible. Progeny is ideal for identification due to its chemical selectivity. To demonstrate the advantages of using a 1064nm analyzer, identification of two separate natural ingredients, turmeric and green tea powder, was performed.
