Analysis of Chinese Herbal Medicines by Microwave Plasma-Atomic Emission Spectrometry (MP-AES)
4 Nov 2014
Microwave plasma atomic emission spectrometry (MP-AES) provides an ideal, low-cost solution for multi-element analysis of traditional Chinese herbal medicines (TCMs). The Agilent 4100 MP-AES is a fast sequential atomic emission spectrometer that uses magnetically-coupled microwave energy to generate a robust and stable plasma using nitrogen gas. By using a nitrogen plasma, the 4100 MP-AES eliminates the need for expensive and dangerous gases such as acetylene, resulting in lower running costs, unattended operation, and removing any safety concerns associated with the use of acetylene and nitrous oxide. In addition the 4100 MPAES eliminates the need to use hollow cathode lamps and when used in conjunction with the Agilent 4107 Nitrogen Generator, operating costs are significantly reduced.
