impurity analysis of tea 茶叶杂质分析
trace gas impurity analysis 痕量气体杂质分析
impurity structure analysis 杂质结构分析
As for assay: analysis results shall be compared, as for test for impurity: if chromatographic graphs are available, peaks of impurities shall be compared.
含量测定应比较两方法的分析结果，杂质测定若有色谱图，则应对比杂质峰的形状。
Through years of practice and theoretical analysis, we obtain the best separation result and the impurity after separation is smaller than 1% and the best result can reach 99.9%.
通过多年的实践与理论分析，获得的最佳分选效果，分选后的杂质可小于1%，即分选效果最高可达99.9%，并且属于完全物理分离，分离后各种材料的性质都不改变，不影响再生利用。
Analysis is made by ICP and SEM of the impurity content and microscopic morphology of the product.
采用ICP、SEM分析检测方法对产物的杂质含量、微观形貌进行了分析研究。
