The relative standard deviation of analytical repeatability was < 5.0 %.The method was validated by comparing the results obtained with those provided by HPLC; no significant difference were seen. eng info:eu-repo/semantics/openAccess Wiley_VCH Determination of Allura Red and Tartrazine in Food Samples by Sequential Injection Analysis Combined with Voltammetric Detection at Antimony Film Electrode info:eu-repo/semantics/article
