20090145204	METHOD AND DEVICE FOR INGREDIENT ANALYSIS - A method for ingredient analysis includes the steps of: providing a database, which stores a plurality of standard ingredient data; analyzing a sample to obtain a plurality of inspection data via a high performance liquid chromatography (HPLC) method; and respectively comparing the inspection data with the corresponding standard ingredient data to analyze all ingredients contained in the sample simultaneously. The method may be applied to a device for ingredient analysis. Thus, by cooperating the database with the HPLC method, all ingredients contained in the sample can be analyzed via at least one analysis procedure so that the procedures for ingredient analysis are simpler and quicker and the accuracy of the analysis result can be enhanced.	06-11-2009
