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,

Atomic Absorption Spectrometry (AAS) - IntechOpen

The instrument used for atomic absorption spectrometry can have either of two atomizers. One attachment is a flame burner, which uses acetylene and air fuels. The second attachment consists of a graphite furnace that is used for trace metal analysis. Figure 1 depicts a diagram of an atom ic absorption spectrometer. Fig. 1.
