本文介绍了一种用C糊电极薄层安培检测器分析抗坏血酸的色谱法。新方法的应用进行了评估，多种维生素制剂，水果，浓缩果汁，乳制品，人尿和血清。在可能的情况下，使用标准氧化还原滴定程序来确证色谱法。与经典滴定法或比色氧化还原法相比，新的分析方法具有简单的样品制备和更高的灵敏度和选择性。采样率高达20/h是可能的，这取决于所研究的特定样品。
A chromatographic for the analysis of ascorbic acid utilizing a thin layer amperometric detector with a C paste electrode is described. Application of the new method is evaluated for multivitamin preparations, fruits, juice concentrates, milk products, human urine and serum. When possible standard redox titration procedures were used to corroborate the chromatographic method. When compared to classical titrations or colorimetric redox procedures, the new assay features straightforward sample preparation and improved sensitivity and selectivity. A sample rate as high as 20/h is possible, depending on the particular sample under study.
