Application of Ion Chromatography in Food Safety  Analysis - 1

INDUSTRY APPLICATION SOLUTIONS The samples are pretreated according to GB/T 5009.33, and after protein precipitation and fat removal, the samples are extracted and purified by corresponding methods. Using CIC-D160 ion chromatograph ,SH-AC-5 > anion column, 10.0 mM NaOH eluent and bipolar pulse conductance method,under the recommended m 10 chromatographic conditions, the chromatogram is as follows. 2. Iodide and thiocyanate in dairy products The milk powder samples are dissolved, mixed with 3% acetic acid and deionized water, filtered by 0.22pm micro-porous filter membrane and treated by IC-RP column. Using CIC-D160 ion chromatograph, SH-AC-11 anion column, 30 mM NaOH eluent and bipolar pulse conductance method, under the recommended chromatographic conditions, the chromatogram is as follows.
