Estimation of some carboxylic acids and inorganic anions in industrial fruit juice beverage by ion chromatography

Carboxylic acids and anions from Industrial fruit juice beverage are detected by measuring the suppressed conductivity detection at baseline ≈0.05 µs cm-1 of complex formed with the Dionex IonPac AS11-HC-5 μm Column. This method, high speed, efficient, cheap, very Recoveries and isocratic phase. Method has been developed and validated for the Estimation of Organic acid and anions using 5 mM sodium hydroxide as mobile phase having PH 9 Mobile phase was pumped at flow rate of 1.0 mL min−1 and isocratic elution using through column. The Conductivity detection method was performed at 12 minutes. Method was successfully following the IC Isocratic. Calibration curve was very linear in concentration range ((2-10) and (3-15)) μg mL−1 for Chloride and Phosphate Consecutively with correlation coefficient Range R2(0.9890-1.0) for inorganic anion and Calibration curve (5-25) μg mL−1 for each carboxylic acid but non-linear (n=3). The determine of lower limits of detection (LLOD) and quantitation (LLOQ) in standard Analyzed for inorganic anions, Also; method detection limit (MDL) for each anion in Organic acids. Recovery was found to be in the range 96.6-101.3 % and precision less than 1 %. Developed method was validate applied for analyzed of standard solution and also to study the interaction of Analysis at room temperature.
