Application Note: QA/QC of Tea Using the Agilent Cary 630 ATR-FTIR Analyzer
4 January 2013
Tea is the most widely consumed beverage after water. Tea leaves contain more than 700 compounds such as flavanoids, caffeine and amino acids. The complexity of the chemical composition of tea, make it very difficult to establish an authentication process and quality control/quality assurance procedures. This application note discusses how the Agilent Cary 630 ATR-FTIR analyzer can reduce operational costs, is lightweight, robust and can thus be used as a portable analyzer to provide molecular fingerprinting of all organic compounds in teas.
