Simultaneous determination of iodide and thiocyanate in powdered milk using ion chromatography with mixed-mode column
混合模式色谱柱离子色谱法同时测定奶粉中的碘离子和硫氰酸根

The contents of iodide and thiocyanate are important detection items in powdered milk quality testing.Due to the complexity of the powdered milk matrix,chromatographic analysis is easily subjected to interference.Acclaim Mixed-Mode WAX-1 column incorporated both hydrophobic and weak anion-exchange properties was used to separate iodide and thiocyanate from interfering substances in powdered milk matrix,and detected by Ultraviolet (UV) detection.After powdered milk was dissolved in water,the protein was prec...
