采用883型离子色谱仪瑞士万通色谱仪对牛奶中的硫氰酸根进行测定。通过一系列牛奶样品实验数据及样品回收的分析,对离子色谱在牛奶检测中的具体应用进行了较详细的论述。结果线性关系好(R=0.9999),回收率高,重现性好。方法可用于牛奶中硫氰酸根的检测进样体积20μL,在样品的前处理部分该方法采用了瑞士万通独有的英蓝渗析技术,大大简化了样品的前处理,结果线性关系好(R=0.9999),回收率高,重现性好。方法可用于牛奶中硫氰酸根的检测。
Determination of thiocyanate in milk using the 883 Ion Chromatograph Synotrex Chromatograph. Through a series of experimental data of milk samples and the analysis of sample recovery, the specific application of ion chromatography in milk detection is discussed in more detail. The results of a good linear relationship (R = 0.9999), high recovery, good reproducibility. The method can be used for the detection of thiocyanate in milk. The injection volume is 20μL. In the pre-treatment part of the sample, this method uses Swanstone unique dialysis technology, which greatly simplifies the sample pre-treatment and results in a good linearity (R = 0.9999), high recovery, good reproducibility. The method can be used for the detection of thiocyanate in milk.
