Document #031020-09. Revision 01, 10 March 2020
Analytes
Acesulfame, Succharine, Aspartame, Caffeine, Benzoic acid, Sorbic acid.
Scope of The Method
The method is intended for the isocratic determination of acesulfame, succharine, aspartame, caffeine, benzoic and sorbic acids in non-alcoholic beverages, beverage concentrates and syrups using simple isocratic 400 bar HPLC system with a conventional UV detector.
The method is capable to determine analytes in the presence of the most of synthetic dyes.
Minimum System Requirements
Solvent Delivery System: Isocratic HPLC pump with 400 bar upper back-pressure limit
Detector: Single wavelength UV detector
Column Oven: Standard column oven
Compartible with all HPLC systems: Agilent, Shimadzu, Waters, Thermo, etc.
General Information On The Method
