Determination of citric acid in fruit juices using HPLC
Standard Calibration . Figure1 displays the overlaid standard chromatograms of citric acid, which eluted from the column at 2.16 min. Based on theintegrated peak a reas from the HPLC chromatogram, a standard calibration plot was created for citric acid as seen in Fig. 2. Figure 1. Chromatogram produced from citric acid standards: 100,
