摘要
利用高效液相色谱法测定了防腐木材中的戊唑醇含量。分析了测定过程中由样品称取质量、样品前处理定容体积、标准溶液质量浓度、液相色谱仪定量重复性、平行试验重复性产生的不确定度的计算方法,确定了防腐木材样品中戊唑醇含量不确定度的最终合成与表示为(494±64)μg/g(k=2)。
In this paper, the content of tebuconazole in preservative-treated woods was determined by high performance liquid chromatography （HPLC）. The methods of calculating the uncertainty of sample weight, sample volume, standard solution concentration, liquid chromatograph repeatability and parallel test repeatability were analyzed. The final synthesis and expression of the uncertainty of the tebuconazole content in preservative-treated woods is described as （494±64）μg/g with k = 2.
