摘 要:采用高效液相色譜法測定丁硫克百威含量,并求出了不確定度值。按照分析丁硫克百威含量的企業(yè)標準,用外標法進(jìn)行測定,建立了相應的數學(xué)模型,確定了分析過(guò)程中引起不確定度的各個(gè)分量。并予以計算得出結論:分析丁硫克百威含量的不確定度主要由3個(gè)部分組成,即標準品與樣品溶液的配制;丁硫克百威標準品的純度;標準品溶液及樣品溶液中丁硫克百威的峰面積。 |
關(guān)鍵詞:高效液相色譜法;丁硫克百威;不確定度 |

Abstract:Carbosulfan content was measured by HPLC,and the value of uncertainty was calculated. A mathematical model was built up and the various factors were determined by applying external standard method. It was concluded that the uncertainty consists of three parts: preparation of the standard solution and the sample solution,purity of carbosulfan standard, chromatographic peak area of carbosulfan in the standard solution and the sample. |
Key words:HPLC;carbosulfan;uncertainty |
