Sequential Injection Chromatography as Alternative Procedure for the Determination of Some Food Preservatives
Sequential injection chromatography for the determination of benzoic acid (BA), sorbic acid (SOA), and salicylic acid (SA) has been investigated. Separation was performed on a monolithic C-18, (5 × 4.6 mm) column which is normally used as a guard column, with 1% acetonitrile: ammonium acetate buffer...

| Summary: | Sequential injection chromatography for the determination of benzoic acid (BA), sorbic acid (SOA), and salicylic acid (SA) has been investigated. Separation was performed on a monolithic C-18, (5 × 4.6 mm) column which is normally used as a guard column, with 1% acetonitrile: ammonium acetate buffer pH 4.5 as a mobile phase at a flow rate of 1.20 mL/min at ambient temperature and with the UV detection at 235 nm. Under the conditions, separation of the three compounds was achieved within less than 3 min. Linear calibrations were found to be 1-100 mg/L for the three: BA, SOA, and SA with detection limits of 1.9, 0.7, and 0.3 mg/L. The developed procedure was demonstrated to be an effective alternative fast and simple method for the analysis of food, fruit juice, syrup, and soft drink samples. © 2011 Springer Science+Business Media, LLC. |
