Application Note: A New Way to Test the Free Amino Nitrogen Content in Alcoholic Beverages with the SPECTROstar Nano
15 June 2012
This note shows that the SPECTROstar Nano is well suited to measure the FAN in beer samples using a microplate or cuvette. The new reduced volume cuvette and microplate based FAN assay deals with a more concentrated ninhydrin stock solution, no extended cooling time is needed and no dilution/quenchsolution is required. There is also no need to run dilutions on beer/wort samples prior to sampling.
